How to set up Face ID, Touch ID, and PIN code lock on the Proton Mail iOS app

When logging in to the Proton Mail apps for iPhone and iPad(ventana nueva) for the first time, your login password will be securely saved on your device so you can easily access and send encrypted email.

To add an extra layer of protection, the Proton Mail app on your iPhone or iPad can be locked automatically with Face ID (if your device has it), Touch ID, or a PIN code. These can be set to lock your account after a certain time or whenever you open the app.

You must choose one option (Face ID/Touch ID/PIN code) when you set up automatic locking. You can’t use a PIN code and Face ID/Touch ID at the same time.

If you forget your PIN or your Face ID/Touch ID prompt fails, the app will ask you to enter your device PIN.
