The Zero-Tap Sign-In standard will require any app supporting user sign-in, optional or mandatory, to automatically restore a user's sign-in state when they move from one Android device to another with the Android Restore Credentials API. This API ensures that when a user opens your app on their new Android device for the very first time, they are instantly recognized and securely signed in without additional taps.  Starting in April 2027, Google Play will require apps to meet the Zero Tap Sign-In requirement to maintain full publishing capabilities and optimal visibility in the Play Store.
