[App] andOTP – Android OTP Authenticator
remote fingerprint unlock
andOTP implements Time-based One-time Passwords (TOTP) like specified in RFC 6238 (HOTP support is currently in beta testing). Simply scan the QR code and login with the generated 6-digit code.
Free and Open-Source
Requires minimal permissions:
Camera access for QR code scanning
Storage access for import and export of the database
Encrypted storage with two backends:
Android KeyStore (can cause problems, please only use if you absolutely have to)
Password / PIN
Multiple backup options:
Sleek minimalistic Material Design with three different themes:
Black (for OLED screens)
Compatible with Google Authenticator
To keep your account information as secure as possible andOTP only stores it in encrypted data files. There are two methods of encryption which can be used: the Android KeyStore or a Password / PIN.
The KeyStore is a system component of Android for securely storing cryptographic keys, the advantage of this approach is that the key is kept separate from the apps data and, as a bonus, can be backed by hardware cryptography (if your device supports this). However, due to that separation, backups with 3rd-party apps like Titanium Backup can not be used if this method is chosen. Such apps only backup the encrypted data files and not the encryption key, which renders them useless. In this case you will have to rely on the internal backup functions provided by andOTP!
The KeyStore is known to cause a lot of problems, so please only use it if you absolutely have to and know what you are doing. In that case please make sure to make regular backups in case something goes wrong. It is always recommended to use a password or PIN instead!
If you found a bug during beta testing, please submit your feedback directly on Github (github.com/andOTP/andOTP/issues) because for some reason I don’t always get notified when new beta feedback is submitted on the Google Play Store.

andOTP is a fork of the great OTP Authenticator app written by Bruno Bierbaumer, which has sadly been inactive for a while. All credit for the original version goes to Bruno. You can find his app here: play.google.com/store/apps/details?id=net.bierbaumer.otp_authenticator
andOTP user reviews :
The best authenticator app, period. Very customizable and the backup feature is sweet. Thank you and keep up your outstanding work.
Works like a charm on my OnePlus 6. I specifically wanted a local backup feature, and it works perfectly. No need to trust my credentials to the server of a mysterious company who didn’t even update their Google Search company details (Authy) or hope I never lose, replace, or damage my phone (Google Auth). Also, dark theme! Yay!

- Fingerprint unlock is already added, you need to switch the “Database encryption” to “Android KeyStore” and then you can use “Device credentials” for authentication, which include fingerprint. Sadly because of the way fingerprint reading is implemented in Android it is currently not possible to use fingerprint unlocking without the KeyStore.
Excellent authenticator with minimal permissions, encrypted backups, and a clean ui. What more could you want?
