Authenticator Pro

Free and open-source 2FA app with encrypted backups
APK source:Github
Google Play:Check if it's there

A free open-source two factor authentication app for Android. It features encrypted backups, icons, categories and a high level of customisation. It also has a Wear OS companion app.

It supports TOTP (Time Based) and HOTP (Counter Based) authenticators using either SHA1, SHA256 or SHA512 hashing algorithms. Mobile-Otp (mOTP), Steam and Yandex are also supported.

2 Factor authentication provides an extra layer of security to your accounts by requiring the use of a one time code to log in. In addition to your username and password, you will need a code provided by Authenticator Pro. So even if your login details are compromised, your account remains safe.


(¹) To scan QR-Codes, the app requires the camera permission.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
