TOTP standard made sense, but mainstream implementation was user-hostile at the start with stuff like Google Authenticator not letting you copy keys, then afterwards still making it unclear under what circumstances they're backed up. Nowadays it's user-unfriendly at best.
I like how we went full-circle to Passkeys which are basically a "remember me FOREVER" button, implemented kinda like SSH keys. Should call it that too, and also ditch the like 4 prompts it gives you first.
