App Lock helps keep your one-time verification codes, app information, and app settings more secure. When App Lock is enabled, you’ll be asked to authenticate using your device PIN or biometric every time you open Authenticator. App Lock also helps ensure that you’re the only one who can approve notifications by prompting for your PIN or biometric any time you approve a sign-in notification. You can turn App Lock on or off on the Authenticator Settings page. By default, App Lock is turned on when you set up a PIN or biometric on your device.
