Flauth

Flauth is an open-source TOTP authenticator for Android. It is designed for people who need to manage two-factor authentication tokens on an Android device. The app provides a privacy-focused, lightweight way to use TOTP codes when signing in to accounts that support them.

Its source code is open, allowing users to inspect how the application works. Authentication secrets are encrypted and stored in Android Keystore, the secure element provided by Android. This storage approach places privacy and protection of token secrets at the center of the app’s design.

Flauth supports exporting and importing data through local text files. It also supports WebDAV synchronization for backups. The interface uses Material 3 and provides adaptive light and dark modes for different display preferences.

In the MirrorNest catalog, Flauth is listed for Android in the Security & Privacy category. MirrorNest mirrors the official build directly onto its own storage. The mirrored file is scanned for malware before publishing, giving readers a checked source for downloading the open-source application.
