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.

You can't beat a FREE, NO ADS, Open Source 2-Factor Authentication App which as of 2026 is the best security. Unless you need a Cloud like Google Authenticator this is the 1 to use!

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
