Pair Locking Your iPhone
If you want to keep your phone secure, enable a long passcode, turn on full device encryption, and turn it off. If you are a US citizen, you can't be turned away at the border or forced to unlock the device. If you're not a US citizen or don't want to be harrassed by customs, bring a burner phone.Tools like Cellebrite can and do take advantage of security vulnerabilities. Turning off pair locking lulls users into a false sense of security and is therefore harmful. Further, only restricting CBP searches to "manual" searches isn't enough and does plenty of damage to your privacy.
