Google Prompt 2FA Requiring Fingerprint, PIN Authentication On Android

Google Prompt is a pretty good 2-factor authentication (2FA) option for the vast majority of users, with Google now adding fingerprint or PIN authentication to the process.

Over the past few days, we’ve started noticing an extra step after tapping “Yes, it’s me” on the fullscreen “Are you trying to sign in” Google Prompt.

Google Play services throws up a standard (similar to what’s depicted below) “Use your screen lock” bottom sheet: google.com needs to verify it’s you. You continue to see Device, Near, and Time details in the background, while you can use fingerprint, face unlock, or PIN to proceed.

In the past, tapping ‘yes’ signs you in on your other device or asks to confirm a number that’s shown. 

This extra security doesn’t hurt and it’s pretty fast, but arguably most people just unlocked their phone to access the Google Prompt. (It’s a bit like the Google Wallet unlock verification introduced last year.) You of course have other 2FA (or 2-Step Verification in Google parlance) options like passkeys, security keys, or authenticator apps.

We’re seeing this 2FA Prompt fingerprint requirement with version 25.02.34 of Google Play services on Android. Play services powers all this on Android, while the Google app or Gmail on iOS is responsible for the Prompt.
