|
|
|
|
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**: All three versions (Google Play, F-Droid and the APKs) 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.
|
|
So make sure you have a **current backup** before switching!
