I currently use Authy on my android and my Linux system.

It syncs every new authenticator between my devices but I dont want to trust companies with my security anymore.

I host a nextcloud instance on my homelab. Does anyone know a good FOSS authenticator that can use my nextcloud to sync between Linux and android? Provided that it is available on both of course.

Thanks for any input!

  • Personally I would use andOTP on my mobile with backups and use OTPClient on my computer. I don’t like having my 2 factor auth stored in the same system as my passwords. Because if the password manager was ever lost or stolen you’d have all your eggs in one basket essentially.

    • Copied from my other comment in this thread:

      andOTP is no longer maintained, so it’s not a good suggestion and you should probably see about migrating to another app. I personally went to Aegis and had a smooth transition.

      • While that is true, there have been many discussions about if there are any known security vulnerabilities or new spec changes that would cause a problem. The consensus from the community is that it is safe to use for quite some time. Not invalidating your points in any way just putting out what I know.
