Comments on 2FA Authenticator (2FAS) for Android

★★★★★ R. Alan Martin · Jul 2, 2026

Absolutely amazing app. Easy to use and setting up on a second phone using the Google Drive backup feature is a breeze. Looking for a terrific authentication app, you're in the right place.

★★★★★ Ramsey Throne · Jan 21, 2026

Highly recommended! I use this app for my 2 mobile phones In my honest opinion it is absolutely worth it! This app security Encrypted way better than Google Authenticator No bugs and absolutely FREE!!

★★★★★ John · Jan 6, 2026

Been using this app for years, opem source take privacy serious, check out comparisons with other apps you will be surprised and switch to 2FAS, keep up the good work.

★☆☆☆☆ Debbie Martin · Jun 16, 2026

Tried to install but unable to finish as don't know where code is supposed to go to finish set up. Just keep getting new codes and unable to finish so uninstalled and looking for better one.

★★☆☆☆ Mathieu “MrSylvestre” Sylvestre · Jan 13, 2026

Backup stopped working unexpectedly Cleared Drive sync, still unable to recreate backups...

★☆☆☆☆ 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
