Ah, ok. Sounds like it’s 2FAuth you’re after. There’s an app for it, too: auff. Or Bitwarden (Vaultwarden if you want everything that Bitwarden have with no paywalls.

If you want to have them locally stored with export and import capability: Aegis.

If you want them in the cloud: Bitwarden. Just make sure to backup the 2FA tokens every now and then.
