GitHub is slowly rolling in 2FA. Any good open source apps that will enable me to activate 2FA token on android? (szmer.info)

If proprietary app is better and more robust I am willing to try it and assess it myself.

I am not a big fan of storing the passwords and 2fa together since if it is compromised, you lose both layers at the same time. But the alternative is not so convenient. But then in security, it is always a balance between the two.

True true. But the auth apps I've seen don't appear to be secure. So if you lose your phone...

And I don't like hw key because I'm afraid I'll lose it.

I have a two layer system in place:

I use Aegis, I have automatic encrypted backups, and syncthing to synchronize the backups to my private server. If I need to reconfigure Aegis, I just import the backup.
I have 2FA backup codes as encrypted text files, which are also synced to my server with syncthing. I have the encryption/decryption software installed on my phone and windows, so I can use a backup code if I don't have access to Aegis.

One issue was I had to write my own apps for windows and android for encrypting/decrypting the text files 😃. You can check them on GitHub: https://github.com/mcanyucel/TextCrypt-Windows https://github.com/mcanyucel/textcrypt-android

They use SHA256 with random IV and random salt. No warranties, though 😅
