...Indeed, users are solely responsible for their data.
TigerSafe also enables you to store the 2-factor authentication mechanism mostly used by modern websites (TOTP 2FA) in a secure way.
Since TigerSafe is particularly sensitive, no binary installation file is provided (because it could be infected by a virus, or have a vulnerability in its dependencies such as the JDK implementation used).
Instead, installation instructions are provided, and a YouTube video for Windows.
Open source fork of the Google Authenticator Android app
...Because secrets are stored on the device and codes are computed locally, it works even without a data connection and avoids server-side dependencies. The UI focuses on clarity and safety cues—timers, account naming, and basic management—to make 2FA adoption accessible to non-experts. For developers, the project doubles as a reference implementation of OTP enrollment, storage, and code generation on Android.
Open source version of Google Authenticator (except the Android app)
Google Authenticator is the open-source counterpart of Google’s one-time passcode apps, implementing industry-standard OATH algorithms such as TOTP (time-based) and HOTP (counter-based) for two-factor authentication. The repository historically hosts code for mobile platforms like iOS and BlackBerry, demonstrating how to generate numeric codes locally without needing network access. Its core purpose is to help services and users add a second factor that’s simple to deploy yet resistant to...
