What if Face ID fails?

You can fall back to your PIN. Set a PIN you'll remember when you turn App Lock on, so a failed scan never locks you out of your own codes.

Does App Lock protect my backup too?

The backup is encrypted separately. App Lock stops someone using the app on your unlocked phone; the backup stays protected in your iCloud account.

How to lock the app with Face ID, Touch ID, or a PIN

Your authenticator holds the second half of every login. App Lock adds a separate check — Face ID, Touch ID, or a PIN — before anyone can see your codes.

Turn on App Lock

Open Authenticator App and go to its settings.
Turn on App Lock.
Choose Face ID, Touch ID, or a PIN.
Set the app to lock automatically so it re-locks when you leave it.
