FOSS-alt to Authy?

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!

dessalines,

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

ikornaselur,

Have you checked out Aegis?

Edit: I missed the Linux requirement, not sure if Aegis works with that in mind

RandomLegend,

Appears to be android only?

lemmyvore,

You can use OTPClient on desktop, it can import Aegis encrypted exports.

It’s what I do, my TOTP codes originate on the phone because I scan the QR codes with it, but Aegis is set to export a backup each time something changes.

A sync app (FolderSync) runs every night and gets the export to my server, where it gets picked up for offline backups.

I load the latest export in OTPClient only as needed, when I run into a 2fa which is not there.

Both Aegis and OTPClient can be set to ask for password each time you open them.
