andOTP - Android OTP Authenticator

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.

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: https://play.google.com/store/apps/details?id=net.bierbaumer.otp_authenticator

andOTP工具的基于时间的一次性密码（TOTP）像在RFC 6238中指定（HOTP支持目前处于测试）。简单地扫描QR码，并用所产生的6位代码登录。

功能的：

＆＃8226;＆＃8195;免费和开源

＆＃8226;＆＃8195;需要最少的权限：

＆＃8195;＆＃8226;＆＃8195;对QR码扫描相机接入

＆＃8226;＆＃8195;加密存储有两个后端：

＆＃8195;＆＃8226;＆＃8195; Android的密钥库（可能会造成问题，请如果你非得只使用）

＆＃8195;＆＃8226;＆＃8195;密码/ PIN

＆＃8226;＆＃8195;多种备份选项：

＆＃8195;＆＃8226;＆＃8195;纯文本

＆＃8195;＆＃8226;＆＃8195;密码保护

＆＃8195;＆＃8226;＆＃8195;的OpenPGP加密

＆＃8226;＆＃8195;伟大的可用性

＆＃8226;＆＃8195;与谷歌身份验证器兼容

备份的：

为了让您的帐户信息尽可能的安全andOTP仅将其存储在加密的数据文件。有两种加密方法可用于：在的Android密钥库或一个密码/ PIN 的。

密钥库就是Android的用于安全地存储密钥的系统组件，这种方法的优点在于，密钥是从应用程序数据保持分离，并且作为奖励，可以通过硬件加密备份（如果您的设备支持该操作）。然而，由于该分离，不能如果选择这种方法用于与第三方应用程序，如钛备份的备份。这样的应用程序只备份加密数据文件，而不是加密密钥，这使得它们失效。 在这种情况下，你将不得不依赖于andOTP提供的内部备份功能！

密钥库是已知会导致很多问题，所以请只使用它，如果你绝对必须的，知道自己在做什么。在这种情况下，请务必在万一出错，使定期备份。 它总是建议使用密码或PIN，而不是！

Beta测试的：

如果您发现了beta测试过程中的错误，请在Github（https://github.com/andOTP/andOTP/issues）直接提交您的意见，因为某种原因，我并不总是得到当新的测试版的反馈所提交的通知谷歌Play商店。
