Description

Aegis is an open-source authenticator app designed for users who prioritise privacy and control over their two-factor authentication (2FA) codes. Unlike cloud-based authenticators, Aegis stores all data locally on the user’s device, eliminating the need for internet connectivity or external servers. This approach ensures that sensitive authentication codes remain under the user’s direct control, reducing exposure to potential data breaches or unauthorized access. The app is free and open-source (FOSS).

Aegis supports standard 2FA protocols such as TOTP (Time-Based One-Time Password) and HOTP (HMAC-Based One-Time Password), making it compatible with a wide range of online services. Users are not required to create an account or provide personal information, enabling anonymous usage and reducing the risk of data exposure.

While Aegis lacks cloud synchronisation, this is a deliberate design choice to enhance security and privacy. Users who require backups can manually export their data to encrypted files, which can be stored securely on their preferred devices or storage solutions.

Migrating TOTP passwords from Google Authenticator or other mainstream authenticator apps is very easy as well, using Aegis' import feature.
