Travel & Flight Security

 Last reviewed on January 12, 2026
 Takes about 30-60 minutes

Who this checklist is for:

  • Anyone traveling internationally crossing the US border to enter or re-enter the country (whether by land, air, or sea).

  • This checklist may also be applicable for domestic air travel within the US as you may be at increased risk of search and adverse consequences (especially if you are not a US citizen).

While we recommend these steps for both entering and exiting the US, you are under much more scrutiny while entering the US, so that is the time to be most cautious. If you're only going to follow these steps once, make sure it is when you enter the US.

We recommend completing the Security Essentials checklist as well.

tl;dr version of this guide - Either bring a secondary phone, backup and factory reset your device, or wipe everything sensitive off your device before you travel. Keep your phone off, disable biometrics, use a randomly generated passcode. Learn your rights. If you're not a US citizen, consider hiding your public profiles before you apply for a visa. If higher risk, get a legal team and have a check-in plan with trusted contacts.

Baseline protections

everyone

This section is for anyone doing activism or advocacy work.

Most of the device searches we've heard of so far in 2025 have involved border police manually browsing a phone looking for things they don't like (criticism of the administration, support for Palestine, etc.) The usually tell you to unlock your phone and rely on your compliance. If you are a US Citizen, you do not have to comply. If you are not a citizen, you risk being sent back to your country of origin if you do not comply.

Know your rights when crossing the border

Your rights depend on your immigration status

Disclaimer: This is just information and not legal advice. Consult a lawyer for advice on your situation.

What are your rights when crossing the border

We have summarized some information below, but we strongly recommend you read these articles to familiarize yourself with the nuances.

Read the following articles to learn your rights:

US Citizens:

  • Cannot be denied entry to the US

  • Must answer: Identity and citizenship questions only

  • Can refuse: Device searches and other questions (but expect delays). Device may be confiscated

  • Right to: Legal representation at the border

Green Card Holders:

  • Cannot be denied entry (without immigration judge hearing)

  • Must answer: Identity and permanent residency questions

  • Can refuse: Other questions and device searches (but you may face delays or deportation proceedings)

  • Don't surrender: Your green card, even if pressured

Visa Holders:

  • Can be denied entry for refusing searches or questions

  • Must answer: All border police questions about travel, background, and purpose if you want to enter.

  • Device searches: Refusal may result in visa revocation and deportation

If you're detained and questioned:

  • Never lie - even small misrepresentations can lead to criminal charges

  • Stay calm and tell the truth

  • Document everything - officer names, badge numbers, questions asked

  • One phone call may be allowed to notify someone.

  • Get a receipt: If your device is not returned, get a receipt so you can attempt to track it down later.

Know the trade offs of not answering questions:

  • While we would generally always suggest that you don't talk to cops, the situation at the border is more complicated. Citizens and non-citizens alike have fewer rights at the border.

  • If you're a US citizen, you can refuse to answer questions (besides the basics listed above), but it may result in long questioning and your device not being returned to you.

  • If you're a green card holder or visa holder, the risks are higher. Read the articles linked above to get a sense of your rights.

Install the latest software updates for your laptop, phone, and apps

The latest updates for your computer, phone, and apps all contain security fixes that help keep your system safe from attackers.

DO: Run updates as soon as they are offered
DO NOT: Keep pressing the “update later” button

All software contains bugs, which are errors or flaws that can lead to various issues.

How to run updates

iPhone

  1. Verify your device is still supported: Check for iPhone models. Make sure there is a "Yes" in the "Supported" column.

  2. Operating System: Settings → General → Software Update

  3. Apps should already be automatically updated unless you have disabled this option.

Mac

  1. Verify your device is still supported: Make sure your Mac isn't on this "obsolete" list. You can check your Mac model by going to the Apple menu → About This Mac.

  2. Operating System: Apple menu → System Preferences → Software Update

  3. Apps installed via the Mac App Store: These apps should already be automatically updated unless you have disabled this option.

  4. Other apps: Check for updates by going to the top menu bar → Click on the app name → Click either "Check for updates" or "About [APP NAME]" or look inside "Settings...". If you don't see an option to update, it may be set to automatically update in the background.

Android

  1. Verify your device is still supported: Checking Samsung models or Google Pixel models depending on your manufacturer. Make sure there is a "Yes" in the "Security Updates" column.

  2. Operating System: Settings → System → System Update (may vary by manufacturer)

  3. Apps should already be automatically updated unless you have disabled this option.

Windows

  1. Update your system: Start → Settings → Update & Security → Windows Update

  2. Verify your device is still supported: After attempting an update, you should be able to see your current operating system version number. Check that version number against this list of Windows versions that are still receiving security updates.

  3. Microsoft Store apps: Make sure you enable automatic updates (on by default).

  4. Other apps: Look for updates in the menu bar under Help > Check for Updates, or search for "Updates" or "About" in the app's settings.

ImportantFully power off your phone & laptop before you approach security checkpoints

Fun fact: Your data is most secure when your phone/laptop is shut down before it's been unlocked the first time.

Almost all phones (and some laptops) are encrypted by default. When cops seize a device they will attempt to bypass the encryption. They'll have the hardest time breaking into a device that has been fully powered down (and has the latest operating system updates). If the passcode/password has been entered even once since booting up, extracting its data becomes a lot easier for them.

How to fully power down your device

iPhone: Press and hold power and volume down buttons → Slide to power off.

Android: Press and hold the power button and select Power off

Laptop:

  • Select Shut down from your system menu.

  • In an emergency, almost all laptops can be forced to power down by pressing and holding the power button for 5-10 seconds

Set your phone passcode to 8 to 10 random digits

It takes years for cops to crack an 8-digit random passcode. They can probably guess your current passcode in less than 5 minutes with automated tools.

DO: Use a random passcode generator to create an 8 to 10-digit code
DO NOT: Use any passcode you thought of yourself (dates, patterns on the keyboard, etc.). Do not use 6-digit passcodes if possible.

How to change your passcode

  1. Generate a random 8 to 10-digit passcode using this random passcode generator. (Don't make one up yourself—humans are bad at choosing randomly!)

  2. Change your passcode:

    On iPhone: Settings > Face ID & Passcode > Change Passcode > Passcode Options > Custom Numeric Code

    On Android: Settings > Security > Screen Lock > Enter Current Lock > PIN/Password > Enter a Passcode

  3. Practice the new passcode at least 10 times in a row right now so are more likely to remember it. (Disabling biometrics will force a passcode request every time you lock the phone.)

  4. Write your new passcode on paper and keep it somewhere safe at home until you've memorized it. Then destroy it after 2–3 weeks. Setting a reminder on your phone can help.

How long does it take to crack a passcode?

Type
Time it takes to crack (average)
Example
6-digit easy-to-guess pattern
Less than 24 hours to crack
333666 (common pattern)
110585 (date pattern for Nov 5, 1982)
6-digit random code
200 days to crack
238253
8-digit random code
40+ years to crack
34780026

Note: These times only apply to phones. Computers can be cracked much more quickly, and need much stronger passwords.

Sources: The estimates in the table above assume real-world observed attempts/second from police forensic hacking tools. If you need more security, use a 10-digit passcode, which will protect you even under the highest-possible cracking scenarios. See the sources linked in the passcode FAQ here.

Enable encryption on your laptop

Ensure your devices are encrypted, and are secured with sufficiently strong passcodes/passwords.

Encrypting Laptops

Encryption may need to be enabled on your laptop:

  • MacOS: System Settings > Privacy & Security [scroll to bottom] > FileVault > Click Turn on... > Save the Recovery Key in your password manager or somewhere secure > Do not enable recovery using iCloud

  • Windows: Settings > Privacy & Security > Device encryption

Note: iPhone and modern Android phones are already encrypted by default.

Print a paper boarding pass and travel documents

So you can keep your phone fully powered off through security and customs.

DO: Power your phone down and use a paper boarding pass
DO NOT: Use your phone as your boarding pass

How to print your travel documents

  1. Boarding passes can usually be printed at the airport

  2. For other travel documents like visitor or work visas or customs declarations, plan well in advance to ensure you can use paper, since some countries make traveling using an app the only convenient option.

Opt out of facial recognition at the airport (and wear a mask)

This helps make it harder for the government to develop a profile on you

DO: Say "I want to opt out of facial recognition" before you hand them your ID

In the United States, citizen have the right to opt out of facial recognition when passing through security (TSA). As of January 2026, non-citizens are now required to comply with facial recognition when entering and leaving the US.

TSA claims to delete photos within 24 hours in most cases. But we have seen many instances in the past where other facial recognition systems have experienced massive data breaches and that could happen here. You gain nothing from allowing the government to scan your face beyond your mandatory ID/passport photo.

YK Hong has an Instagram reel showing how to opt out and the reasons why it matters. We recommend their content on biometric theft.

How to opt out of facial recognition at the airport

You can and should opt out of facial recognition every time it is offered:

  • Security screening (TSA, etc)

  • The gate where you're boarding (some airlines are using facial recognition at the gate)

  • Immigration and passport control (they have a camera to take your picture, but you can opt out).

It's easy to opt out:

  1. Simply say "I want to opt out of facial recognition."

  2. Do not hand your ID over or put it in the scanner machine until the agent acknowledges your request. Otherwise you may be locked into the facial recognition process)

  3. Wear a mask for further protection when going through the airport. If you're wearing a mask, you will need to take it down so the TSA agent can make sure your face matches the photo on your ID.

  4. If you're ever not sure what to do, just ask an agent nearby: "I'd like to opt-out of facial recognition, where do I go to do that?" They will often bring you to a separate line for manual screening (which sometimes gets you through faster!)

Enhanced protections

medium-threat

This section might be for you if you are outspoken about immigration, Palestine, or other issues the government is targeting.

Note - Deleting data doesn't mean it's gone: This section suggests deleting apps and data. However, governments can use forensic tools to access data after it has been deleted. So guidance below offer reliable protection only against an adversary manually searching through your device, which is the most common situation at the US border.

If you're at higher risk and think the cops might invest more resources to access the data on your phone/laptop, make sure to follow steps in the High-profile protection section below in addition to what's here.

Uninstall apps with sensitive data (email, docs, social media, etc) on phone and laptop

Remove anything you don't want to be easily searchable by the cops.

The less you have on your device, the better.

Which apps to uninstall

Consider uninstalling the following apps (on phone and laptop) if they have any sensitive data in them:

  • Email & Calendar apps (if you're using your phone's built-in apps you might need to sign out from your phone's Settings > Accounts)

  • Docs & notes (Google Docs, Evernote, etc.)

  • Other communication apps (Slack, WhatsApp, etc.)

  • Google Maps (or at minimum disable Location History)

  • Social Media apps

Tip: Hide the app: You can also move an app to a hidden folder. Instructions: iPhone and Android. This will only provide a slight advantage since most cops would know to look in this folder. Deleting is much more secure.

You may also want to delete specific content from apps that you leave installed:

  • Notes in the built-in Notes app on iOS

  • Individual text message threads

  • Move sensitive photos to a Hidden Album (or alternately, back them up somewhere and remove them entirely from your device)

Secure your Signal app before crossing a border

Signal is an important app that we recommend using to keep your communications secure.

Securing Signal at the border

How to secure signal for a border crossing

  1. Delete Signal threads with sensitive communication

  2. Leave Signal groups that you're in with people you don't want to be easily associated with. (Make a list of these groups and ask an admin in the group to re-add you after you cross the border.)

  3. Hide the app: You can move an app to a hidden folder. Instructions: iPhone and Android. This will only provide a slight advantage, because most attackers know to look in this folder.

Tip: If you've kept disappearing messages turned on for all your threads, you might not have much deleting to do!

If you're willing to uninstall Signal

While uninstalling Signal is the most secure option, it can be very disruptive.

Because it is such an inconvenience, we only recommend uninstalling Signal if you have a lot of high-risk messages. If you do, you might consider following the "High Security Approach" section instead.

Benefits of uninstalling Signal:

  • Your communications are more protected from a basic search

Downsides to uninstalling Signal:

  • Your entire message history is deleted

  • Your groups are not findable until someone messages you again in that group

If you're bringing your laptop, consider uninstalling the Signal desktop app as well.

Uninstall your password manager (remember to back up your login credentials!)

Make sure to uninstall from your phone and your laptop.

If you don't use a password manager: Remove whatever method you use to store your passwords (like a notes doc or spreadsheet) - but make sure it's backed up elsewhere!!

How to safely remove your password manager

  1. You must make absolutely sure you have memorized (or written down) your master password if you're uninstalling the app from all your devices. If you use 1Password, make sure to also write down your "Secret Key" and store it somewhere safe. You can travel with this information if you do not think your possessions will be searched.

  2. Don't delete your Two-Factor Authentication (2FA) codes if you use an app on your phone for that. Those are hard to restore and not useful unless someone also has your password.

If you need passwords while traveling:

  • Write your master password down on paper (and 1Password secret key if applicable). Conceal the passphrase innocuously (in a paper journal or dayplanner). Log back in after crossing the border. Burn this paper as soon as you're done with it.

  • Alternatively, keep your passphrase (or part of it) with a trusted human who can share it with you on a secure channel (like Signal) from a safe location.

Hide or deactivate social media accounts

Helps protect you if they lookup your social media accounts online (without needing your device)

Unless you're intentionally trying to maintain a widely public social media presence, it's a good idea to lock down your accounts at least temporarily. (Consider doing it long-term for more privacy and security. Or just deleting the accounts outright if you can manage it.)

Visa applicants: If you are applying for a non-student visa, make sure you hide your social media before you apply. We know from the case of an Australian journalist that waiting until the week before you fly might mean they have already looked you up online.

Student visa applicants: In June 2025, the State Department started requiring all student visa applicants to make their social media profiles public. If this applies to you, you may want to actually delete old posts using a tool like Block Party.

How to hide or deactivate social media accounts

Instructions:

  1. X / Twitter: make it private or deactivate it

  2. LinkedIn: make it private or deactivate it

  3. Instagram: make it private or deactivate it

  4. Facebook: make it private or deactivate it

  5. TikTok: make it private or deactivate it

  6. Consider hiding public other public posts like blog posts, YouTube videos.

Consider using Block Party to assist with this process; Cyd.social can also help you make a local, private backup first!

You are not obligated to provide your social media handles to CBP (Customs & Border Patrol) or to the TSA. You can say that you are not comfortable answering or that you do not see the relevance of the question to your travel. Do not volunteer additional information for any question.

Log out of websites that have sensitive information (phone and computer)

If you're not signed in, you have more legal standing to not reveal your password

Which websites to log out

Remember to log out on both your phone and your laptop.

Websites to log out of:

  • Email and calendar (work and personal)

  • Docs (Google Drive, etc)

  • Social media

  • Discussion forums (Reddit, etc)

And anything else you wouldn't want the cops looking at.

Leave Signal groups that might put others at risk

This helps protect your network if your phone is confiscated.

If your phone is confiscated by law enforcement, one of the biggest risks is exposing your entire network. Even if people aren't using their real name on their Signal account, there is still a unique ID behind every Signal username. And the cops can use this to correlate someone's identity across many seized devices.

You need to both leave AND delete the group:

  • If you only leave the group, old messages stay on your phone as well as the history of who was in the group.

  • If you only delete the group, new messages will still come through and the thread re-appears.

How to leave AND delete a Signal group

  1. Make a plan to re-join afterwards: When headed into a situation with possible arrest, make a list on paper at home or somewhere safe of all the groups and who you need to message who can re-add you after the action or border-crossing is complete.

  2. To leave the group: Signal > [Group] > Tap the group icon at the top > Click “Leave group” at the bottom.

    • If you're the only admin, you have to either remove all members or assign another admin.

  3. To delete the group from your phone: Signal > Main screen > Swipe left on the thread > "Delete.”

    • This won't delete it for anyone else.

Security hygiene tips:

  • Set a recurring remind to clean up your Signal thread every 3 months.

  • Make sure you take note of which groups you are leaving and who you can ask to re-add you after the action.

Note: If you find this process very annoying and cumbersome (because it is!), that's another good reason to use a secondary phone for actions. That phone would only ever be in the one or two groups needed to pull of the action that day.

Install a trusted VPN with ad-blocking to make it harder for cops to do warantless survillance

A VPN makes it harder for websites to track you and prevents your internet provider from logging your traffic.

DO: Install a trust VPN and keep it on. We recommend Mullvad VPN ($5/mo) or IVPN ($6/mo).
DO NOT: Use a random VPN you find online. Nord VPN, Surfshark, ExpressVPN, etc. are popular but not trustworthy.

Anytime you connect to the internet (phone or computer), your internet provider is revealing your approximate location to every site/app you use.

We know that law enforcement agencies are using tools that to track your location using data gathered from apps you have and ads you see. Using a VPN with ad-blocking features enabled makes it much harder for them to track you. Also, police can get a subpoena for your internet traffic from your internet provider.

A VPN (Virtual Private Network) helps mask your location and makes you slightly harder to identify.

A VPN with ad-blocking enabled is especially important on your phone.

Options: All of these are very trustworthy options.

  • Mullvad VPN (top recommendation) -Better privacy since payment info isn't stored, but you need to manually pay each cycle.

  • IVPN can be easier because it automatically renews.

  • Proton VPN has a solid free plan, but it is only for 1 device. To get ad-blocking, you need a paid plan. (See our note regarding concerns about the Proton CEO and why we still offer Proton options.)

How to set up Mullvad VPN

Mobile app

  1. Create an account number and write it down: Create a Mullvad account number (there is no password) and write it down somewhere safe like your password manager.

  2. Pay (aka "Add time"): There is no automatic renewal, so all payments are manual. Paying yearly can make things easier so you don't have to remember.

  3. Install the Mullvad mobile app (iPhone, Android) and use your Account number to sign in.

  4. Enable ad-blocking: Gear Icon ⚙️ > VPN Settings > DNS Settings > DNS content blockers > Enable Ads, Trackers, and (optionally) Malware

Desktop app

  1. Install the Mullvad desktop app (Mac, Windows). Get the Account Number from the phone app.

  2. Enable autoconnect: Find Mullvad in your toolbar > Gear Icon ⚙️ > VPN Settings > Enable "Launch app on start-up" and "Auto-connect"

  3. Enabled ad-blocking: Find Mullvad in your toolbar > Gear Icon ⚙️ > VPN Settings > DNS content blockers > Enable Ads, Trackers, and (optionally) Malware

We recommend keeping your VPN on at all times unless you're having trouble connecting to a site (see below).

Note: Instead of a credit card, you can also order a voucher card for Mullvad or IVPN so that your identity is even more protected. (Yes, we hate Amazon too, but that's the only place online you can buy these cards.)

Downsides to using a VPN

  • You will encounter more CAPTCHAs on websites

  • Some websites may block VPN access, and you'll have to disable it and remember to re-enable it later

  • Some streaming services might not work

If you experience odd behavior on websites, always try turning off the VPN temporarily to see if it will load.

Note: You must use a trusted VPN that doesn't keep logs of your internet traffic and will push back on government requests. We've vetted our top recommendations.

High-profile protections

high-threatThis section is for you if:

  • You are are not a natural-born US Citizen.

  • You are doing activism, community organizing, or other work against the administration that puts you in a position of power or public prominence.

  • You are a public figure (artist, scientist, human rights lawyer) that has spoken out very publicly against the administration.

  • You have any other reason to think you might be a more of a target than most folks crossing the border.

This section assumes that border agents might go further and attempt to hack your device using forensic extraction tools. The best approach in this case is to bring a secondary device (sometimes called a "burner phone" or "travel laptop"). Because you can be denied entry or have devices seized indefinitely, your goal should be to travel with devices that you would be able to unlock and display to a border agent. Avoid if at all possible the device being taken from your hands or out of your sight.

Prepare a secondary phone (and keep very little information on it)

If you bring a phone with very little data on it, it won't matter much if they get access to it.

How to set up a secondary phone

Take the Secondary Phone Checklist steps, but with the following changes:

  1. Instead of getting a SIM with a US phone number, search online for prepaid SIMs you can buy in advance for the country you are going to.

    Or alternately, just use the phone on Wifi without a SIM or phone number until you arrive in the country, then buy a SIM card near the airport when you arrive. For eSIM-enabled phones, alosim.com can be a convenient option.

    • Only do this when departing the US. When re-entering the US, make sure before you pass through customs you will be able to access either airport WiFi or an active SIM to communicate with your emergency contacts.

  2. As stated in the Secondary Phone Checklist, store only essential, absolute minimum information on the device.

  3. If you set up Signal with a new phone number (from your new SIM card), make sure you add only your most essential contacts.

  4. Do NOT sign into any websites with sensitive information: email, social media, etc.

Alternate approach: If you can't access a secondary phone, you can also backup your entire phone to your computer (iPhone, Android) NOT the cloud. Then you can factory reset your phone and use it while on your trip. When you return, you can then do another factory reset and restore from the backup. If you take this approach, ensure you have a backup of your backup in a secondary location. Backing up an iPhone to the cloud with Advanced Data Protection could be considered safe.

Prepare a secondary laptop (if applicable)

If you can manage without a laptop, that's safer. If you need a laptop on your trip, we suggest getting a secondary device and keeping very little data on it.

Setting up a secondary laptop

  1. Try to find an old one from a friend that you can use or buy a cheap one online.

  2. Factory reset the device (Mac, Windows)

  3. Set up the device without signing into your typical Apple/Microsoft account (which risks syncing a lot of data to the machine).

  4. Install only apps that have data on it that you'd be okay displaying to a border agent.

  5. Do NOT download or install secure apps like Signal, your password manager, or apps with a lot of information like Google Drive (for desktop) or Gmail.

  6. Do NOT sign into any websites with sensitive information: email, social media, etc.

After you cross the border, if you install additional apps, make sure you remove them again before you re-cross the border.

Generate a random passphrase for your laptop (if you're bringing it)

The encryption on your devices is only as strong as your passphrase. If you think of a passphrase yourself, it is likely much easier to crack than one that is randomly generated.

How to set a randomly-generated laptop password

  1. Generate a computer-generated, random passphrase using a site like StrongPhrase.net

  2. Change your password on your device:

    • macOS: System Settings > Users & Groups > Click the circle "i" icon ℹ️ next to your account > Click "Change..." > Use the passphrase you generated above

    • Windows: Settings > Accounts > Sign-in options > Password > Change > Enter current password > Use the passphrase you generated above

Make a safety plan with 2+ emergency contacts

Make sure someone can help you if you're detained at the border.

How to make a border crossing safety plan

  1. Contacts: Ask 2-3 people to act as your emergency contacts

  2. Contact information: Make sure you memorize their phone numbers. Do this a week or more before you depart if possible.

  3. Group: Put them in contact with one another so they can coordinate if they need to support you.

  4. Arrival/departure information: Let them know your departure/arrival times and your flight number so they can track your flight online in case there are delays.

  5. Legal information: Also, tell them your government ID number, passport number, full legal name, and date of birth. These can be helpful if you are detained.

  6. Reception: Make sure you will either have WiFi at the airport or a functioning SIM card.

  7. Legal support: Tell them how they should go about finding legal support for you if you are detained. Either identify a lawyer who you already have a relationship with or tell them how to find lawyers who support activists (check out the ACLU and the NLG). If you're at especially high risk, then make sure you've made contact with a lawyer in advance and let them know who your emergency contacts are.

  8. Check in plan: Let them know when and how you will contact them before and after you go through US customs and immigration at the border. Ensure they have clear steps to follow if you do not check in.

    For example:

    "I will message you on Signal after my flight lands and before I go through customs. I'll message you from 555-123-4567. I started a Signal group for us already. If it's been more than 1 hour since you last heard from me, notify my legal support. If my lawyer agrees it is strategic to do so, put out a public call for support. Please water my plants and let my work know I'm delayed in transit."

Write down contact information for anyone you need to be in touch with

How to manually track your contacts

  1. Instead of syncing all your contacts from your main phone, write down on paper (or digitally) the most important contacts that you will need on your trip. Include their phone number and email address.

  2. Make sure to let them know what phone number and/or email address you will be contacting them from, and consider a pre-arranged check-in question/answer so they can verify that it is you and not someone impersonating you.

Fully disable face/fingerprint unlock (biometrics)

Protects you if the cops try to force you to unlock your phone.

Cops can try to force you to unlock your phone with your face/fingerprint (though this usually requires a warrant).

You have stronger legal standing with a passcode than with biometric unlock.

How to disable face/fingerprint unlock

On iPhone: Settings > Face ID & Passcode > Disable "Use Face ID for iPhone Unlock" (you can leave the rest enabled)

On Android: Settings > Lock Screen (or Security) > Biometrics and Security > Disable both "Face Recognition" and "Fingerprint Unlock" for unlocking your phone

Caveat: Face/fingerprint unlock can make it easier to use a strong passcode without typing it every time. If you feel you have to choose between a long passcode and disabling biometrics, we recommend a longer passcode.

Follow all the steps in the first two sections of this guide

All the steps in the Baseline Security Approach and Medium Security Approach sections above still apply even if you're using secondary devices.
