And then losing access to everything when moronic automated Google systems ban your account for $REASON with no chance to appeal it.
I recently ran into an interesting problem -- my Microsoft account (used as a spam lightning rod) borked a passkey stored on a Fido token and refused a paswordless sign in. Same thing happened with a second backup token made by a different company. If I didn't have a password fallback, and that account was important, I would have a massive problem with no way to solve it. But the world has not yet gone completely insane, so I fired up my trusty KeePassXC and was in in less than a minute.
