|
|
|
andOTP is a two-factor authentication App for Android 4.4+.
|
|
|
|
It implements Time-based One-time Passwords (TOTP) like specified in RFC 6238.
|
|
Simply scan the QR code and login with the generated 6-digit code.
|
|
|
|
This is a fork of the great OTP Authenticator app written by Bruno Bierbaumer,
|
|
which has sadly been inactive since 2015. All credit for the original version
|
|
goes to Bruno.
|
|
|
|
## 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
|
|
* Plain-text backups
|
|
* Encrypted backups using OpenPGP
|
|
* Sleek minimalistic Material Design
|
|
* Great Usability
|
|
* Compatible with Google Authenticator
|
|
|
|
## Backups:
|
|
|
|
To keep your account information as secure as possible andOTP only stores it in
|
|
encrypted data files. A part of the encryption key used for that is stored in the
|
|
Android KeyStore system. 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 with andOTP. Such apps only backup the encrypted data files and not the encryption
|
|
key, which renders them useless.
|
|
|
|
**Please only use the internal backup functions provided by andOTP to backup your accounts!**
|
|
**Everything else WILL result in data loss.**

|
|
|
|
**Warning**: The APKs and the Play Store version are not compatible (not signed by the same key)!

You will have to uninstall one to install the other, which will delete all your data.
