Bugfix: Fix crash when using the tags drawer (Issue #856)



两步验证(2FA)应用 可用来替代Google Authenticator



推荐使用'设备凭据'作为身份验证 可以使用设备指纹识别, 如果你发现程序有更新记得评论区at我一下, &不会更新pre-release版本!


andOTP is a two-factor authentication App for Android 4.4+. It implements Time-based One-time Passwords (TOTP) and HMAC-Based One-Time Passwords (HOTP). Simply scan the QR code and login with the generated 6-digit code.

This project started out as a fork of the great OTP Authenticator app written by Bruno Bierbaumer, which has sadly been inactive since 2015. By now almost every aspect of the app has been changed/re-written so the fork status of the Github repository got detached upon user request. But all credit for the original version and for starting this project still goes to Bruno!


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, 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

>>>Supported algorithms<<< 

TOTP (Time-based One-time Passwords) as specified in RFC 6238 | HOTP (HMAC-based One-time Passwords) as specified in RFC 4226


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.

>>>Opening the backups on your PC<<<

OpenPGP: OpenPGP can be used to easily decrypt the OpenPGP-encrypted backups on your PC.

WebDecrypt: JavaScript-based decryption of the new password-protected backup format in the browser (source code).

andOTP-decrypt: Python script written by @asmw to decrypt the old password-protected backup format on your PC.

>>>Automatic backups<<<

BroadcastReceivers: AndOTP supports a number of broadcasts to perform automated backups, eg. via Tasker. These will get saved to the defined backup directory. These only work when KeyStore is used as the encryption mechanism. #01 org.shadowice.flocke.andotp.broadcast.PLAIN_TEXT_BACKUP: Perform a plain text backup. WARNING: This will save your 2FA tokens onto the disk in an unencrypted manner! #02 org.shadowice.flocke.andotp.broadcast.ENCRYPTED_BACKUP: Perform an encrypted backup of your 2FA database using the selected password in settings.
