**Multifactor authentication apps** implement a security standard adopted by the Internet Engineering Task Force (IETF) called **Time-based One-time Passwords**, or **TOTP**. Bu, web sitelerinin sizinle bir sır paylaştığı ve kimlik doğrulayıcı uygulamanız tarafından web sitesinin kontrol etmesi için oturum açarken girdiğiniz geçerli saate dayalı altı (genellikle) basamaklı bir kod oluşturmak için kullanılan bir yöntemdir. Typically, these codes are regenerated every 30 seconds, and once a new code is generated the old one becomes useless. Even if a hacker gets one six-digit code, there is no way for them to reverse that code to get the original secret or otherwise be able to predict what any future codes might be.

We highly recommend that you use mobile TOTP apps instead of desktop alternatives as Android and iOS have better security and app isolation than most desktop operating systems.

## Ente Auth

**Ente Auth** is a free and open-source app which stores and generates TOTP tokens. It can be used with an online account to back up and sync your tokens across your devices (and access them via a web interface) in a secure, end-to-end encrypted fashion. It can also be used offline on a single device with no account necessary.
