Literally Windows and MacOS has this built-in. But you’re right, the hard part is losing the token or it breaking. I slammed one Yubikey in a door, breaking it in half. I’m on my backup but I still find services where I didn’t enroll the backup and have to go through a lengthy process to regain access to my account (or create a new one).
