I use Bitwarden. I need none of the convenience of passkeys, and I am able to login on a third system just by hand-copying a password, which I cannot do with passkeys. So why should I prefer passkeys anyway?

Passkeys have some benefits, but the major reason they exist is vendor lock-in.

The main reason they exist is that the vast majority of people don't create secure passwords and 2FA isn't always reliable. Passkeys may not be for someone like you (and me).

Passkeys can’t be accidentally hand-copied into a phishing page.
