Please note that a connection to your Android device is required.
Comments and Reviews
My search to find the best TOTP app has finally come to an end, as Authenticator Pro is simply the best! Despite “Pro” being in the name, it is entirely free and open source. Plus, it takes great measures to secure user data, like encrypted backups, biometric or password unlock, and tap to reveal code.
It is also dead easy to use with a customizable and material design.
It looks great and has many import and export possibilities, I just wish it had a better name. The only thing missing for me is a browser extension like the one from 2FAS
