Molly

Molly is an independent Signal fork for Android.

Back in 2018, Signal allowed the user to set a passphrase to secure the local message database. But this option was removed with the introduction of file-based encryption on Android. Molly brings it back again with additional security features. Molly connects to the Signal server, so you can chat with your Signal contacts seamlessly. Please remember to review their Signal Terms & Privacy Policy before signing up. Every two weeks Molly is updated to include the latest features and bug fixes from Signal.

Versions Molly, like Signal, uses Google’s proprietary code to support some features. Molly-FOSS is the community effort to make it 100% free and open-source.
