About this app

andOTP is currently unmaintained, please check GitHub for additional details.

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.

Features:
•  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:
 •  Plain-text
 •  Password-protected
 •  OpenPGP-encrypted
•  Sleek minimalistic Material Design with three different themes:
 •  Light
 •  Dark
 •  Black (for OLED screens)
•  Great Usability
•  Compatible with Google Authenticator

Backups:
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!

Beta testing:
If you found a bug during beta testing, please submit your feedback directly on Github (https://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.

Open source:
This app is fully open source (licenses under the MIT license), you can check out the source on GitHub: https://github.com/andOTP/andOTP

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. It has since been removed from Google Play, but you can still find the code of his app here: https://github.com/0xbb/otp-authenticator

Fantastic app. I've been using it for about 2.5 years now. I switched to this app because it had some really nice features that I needed. The most important feature being encrypted backups that can easily be created and restored. I have been worried though about this project being abandoned but it seems the developer is writing a new one. Edited because it seems direct backups to Drive still work which is great!

The app and its features are great. The thing I'd definitely change are its color combinations extremely hard to read, specially if users have color blindness (I tested that with a daltonic user: huge nightmare!) Another thing: where to help on translating the app to Spanish and French ?. Last: any news on the rewrite from scratch of the app, since 2018 ? Thanks, thumbs up!

Thank you for your review. I am currently in the process of rewriting the app from scratch under a new name and with a new look. I will make sure to pay better attention to the color scheme for that. If you want to contribute to the translation you can head over to Crowdin: https://crowdin.com/project/andotp
