Comments on Google Authenticator for Android

★★★★★ Shyman85 · Sep 29, 2026

Google authenticator is my optional 4 to sign-in google. Option 1 Recovery Email -- Option 2 Backup Codes -- Option 3 Passkey -- Option 4 Google Authenticator

★★★★☆ Steve Olson · Oct 22, 2026

I wish you could add an account alias of your choosing, so it was easier to keep track of ones that aren't intuitive or appear similar to others.

★★★★★ Abdul Rahman Khan · Oct 6, 2026

MANDATE YO HAVE FOR 2FA & GOOGLE ACCOUNTS SECURITY!! REALLY BLESSED TO JAVE THIS APP!!

★★★★★ Yousef Saber · Sep 30, 2026

Your app lacks an important feature, it doesn't back up all the credentials and codes to my Gmail account to restore them automatically on a new device.

★☆☆☆☆ Rove McClain · Oct 10, 2026

There is a huge security risk in the Authenticator app on the biometrics screen!!!! If you press the back button without authenticating, the biometrics authentication is dismissed and goes straight to displaying the two-factor verification codes. Totally defeats the purpose!!

★★☆☆☆ Aasim Mohsin · Sep 29, 2026

I can't open it its open but I cannot see codes just see Use fingerprint button but my fingerprint is not working 😒

★☆☆☆☆ A Google user · Oct 17, 2026

I'm trying to keep things secret since I've been hacked and people are synced to my accounts. Why don't you just advertise on Facebook? People are synced to my accounts. Devices I no longer own are synced to my accounts and devices and every other thing possible. Why do you wait until I've completed my task to tell me that all the scoundrels still have more Access than me. You can't prevent people synced to my accounts. I have cataract's, and you're a retard for making me do your work.

★☆☆☆☆ Pouya Hezaveh · Sep 29, 2026

I've exported from my code from previous mobile few years ago (before it wasted) Now It's not possible to scan those QR codes and recover my accounts 😭😡🤬🤬 Don't put an option that doesn't work.

★☆☆☆☆ Alan O'Dowd · Oct 17, 2026

Woeful app, absolute mess of the user interface with limited options for adding 2-step authentication. Scanning a QR code from a phone is easy but virtually impossible when it's on the phone screen. More Google Junk.
