Comments on 2FA Authenticator (2FAS) for Android

★★★★★ Ilias Mithrantir · Feb 23, 2026

Very good and easy to use app for 2FA. The ability for cloud backup is useful. Also, no ads.

★★★★★ Allan · Nov 16, 2025

Excellent authenticator! I've been using it for a few years and have encountered no problems. I especially like the Google backup feature that has the option to password protect the backup, biometric and PIN access, dark theme, and the ability to automatically insert the code within a browser without copying and pasting. I've tried many other authenticators, but I find this one outshines the others.

★★★★☆ Dohraymee Fasolati · Nov 10, 2025

The 2FAS app works very well. It's easy to use. I would like more than a 6 digit password and allowance to also use letters. The other thing I believe would be very useful 8s a note field for each token.

★☆☆☆☆ James Kowal · Mar 8, 2026

I just can't use this inadequate garbage anymore that they don't bother to make basic improvements on. Can stupidly only delete one at a time, no multi selection. And Google Drive synch is trash, always synchs wrong way. Can't even take a QR code photo of all tokens to save on other device. Its taking me 3 hours to do what should be a basic task, baking up like 4 mere kb of data to another phone. Absurd

★☆☆☆☆ Goorden Manaka Manaka · Feb 9, 2026

I can't be the only one with a sad story I activated my 2fas to one of my accounts it worked a couple of times and stopped working I have the code and QR code but still no access.
