Ente Auth is a free and open-source app designed for two-factor authentication, enabling users to create and manage time-based one-time passwords that enhance security beyond standard password protection. With features such as end-to-end encrypted backups, users can safeguard their codes without the risk of losing them, ensuring that their information remains confidential, even from the service provider. The app offers seamless synchronization of codes across mobile, desktop, and web platforms through secure encrypted channels, and it also allows users to import existing 2FA tokens easily by scanning QR codes or through manual input. Additionally, users can benefit from functionalities like offline code generation, tagging and searching for codes, pinning favorites, and a quick display of the next code for expedited logins. All backups utilize robust, audited cryptography, ensuring that only the user has the keys to access their 2FA secrets, and there is an option to share codes securely with colleagues through encrypted links that can be set to expire. Furthermore, Ente Auth is designed to enhance user experience by providing a clean interface and intuitive navigation, making it accessible for everyone, regardless of their technical background.
