Using biometric data to unlock personal devices. Don’t do it.

You might think that using a biometric two-factor authentication is safer, and this may be true if your adversary is remote, but what if your adversary is physical?

Imagine you cross borders and border security decides to search you.

They access your devices and see you have cryptocurrency. If you use biometric data to access your devices and accounts, it won’t be hard for an attacker to physically “coerce” you into scanning your fingerprint or face to gain access to your devices.

In this case, it’s much safer to use password protection on all your devices, backed with TOTP (time-based one-time password) authentication. You can even take things a step further by setting your phone to delete all data after a certain amount of failed attempts. This way someone can’t brute force your password to gain access to your device.
