How is that different from accidentally deleting your keepass database? Or forgetting your password? I think it’d be easier for me to forget than find myself trying to flush all my hw tokens…
Everything is SYNCED immediately.
What if you have a ransomeware that destroy everything on the same day your house and all backups burn down. And you cant get it from immutable backups as you wrote that decryption key in paper. And the bank will not allow you to access it as the govt deported you elsewhere.
And since I have at least two at all times, the possibility of one of them breaking changes… not much really.
Paper can burn or get tossed, backups files can go corrupt, and I really don't understand what is that extra risk hw keys introduce…
There is at least one valid (in my opinion) reason to not like hw keys though: they cost real money to acquire, so you probably want an extra margin in your budget for the unlikely case they indeed decide to break.
Also... Is flushing your whole keys down the toilet a problem you run into often?
It's a potential catastrophe I'd like to avoid if possible, but the catastrophe is not inherent to any other key I have.
House key: Make new copy for 10 USD. Alternatively, get a locksmith to unlock the door and change the lock. Even more alternatively, break a window or door. I still get into my house.
Car key: Make a new copy for >10 USD. Alternatively, call roadside assistance and get them to tow me somewhere I can get a new key. More inconvenient, still very possible.
TOTP 2FA and passwords: Password databases can be backed up, and so can TOTP seeds. It's inconvenient to do so, but I can at least still just leave copies around everywhere I can, so that it's extremely unlikely that I'll be completely locked out.
Yubikey: Making copies is literally impossible, so I'll need to buy two or three keys from the get go, and get them all out every time I need to add a new key. This is a huge inconvenience that no casual user will ever do (they might do 3-2-1 if it was set-and-forget, but Yubikeys aren't). If I don't do this, I lose permanent access to my accounts. There is no safety valve built in to the system. If I lose my key, I'm fucked.
