Christian loves a GPL3 Two Factor Tool

Greetings. I'm listening to Coder Radio 491 and you were talking about 2FA, One of my biggest fears was loosing access to Google Authenticator (especially when I had a device requiring maintenance and I did not think about it in advance). 

Then I've learned about Aegis. A GPL3 authenticator for Android that supports multiple devices, automatic backups AND(!!!) exporting your vault, so if you loose a device or want to enable another one, you can simply import your vault (no clouds required).

Saved me already once or twice.
Cheers.
