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!

    Keepass supports OTP, and exists on every platform. I use KeepassDX on android.

      This is what I used as well (KeePassXC specifically), with Syncthing sharing the .kdbx file across devices.

      I’m using this with Nextcloud through WebDAV.

      There is a keepass app in Nextcloud to access your keepass database using a web browser (keeweb), keepassXC has a client for Linux, Mac and windows (and all of them work great) and there are many apps for iOS and android.

      I use the free version of Strongbox with WebDAV and I haven’t had any problems.

      You can just backup the keepass database file and you can also have several databases. Each database has its own password.
