You’ll need to be on version 6.4.22+ on iOS to try this out. If you don’t have the Microsoft Authenticator app yet, get it here. With our latest release, as part of our effort to make your sign-in experience even more secure, App Lock will be enabled by default if you’ve set up a PIN or biometric on your device.

Now, if App Lock is enabled, when you approve any notification, you’ll also have to provide your PIN or biometric.

Last month, we expanded App Lock’s protection. A few years ago, we released our App Lock feature in response to feedback that you wanted to make sure your app was secured by a PIN or biometric. We’re always listening to your feedback about Microsoft Authenticator and what we can do to make the app more secure and easier for end users.
