Exactly! Whereas passwords are extremely flexible and can be stored, managed, and written down in numerous ways that are vendor-independent. Want to store your passwords on sticky notes in a safe? Go ahead! Want to use Bitwarden? Yep, you can. KeePass for offline storage? Yes! With good password hygiene (128-bit entropy, never reusing passwords) there is virtually no risk, especially with 2FA added.
You can (and should) do the same with passkeys. Like SSH keys, they're just text.
Save a passkey in Bitwarden, then export your vault as JSON. You'll see a nice plain text JSON block with your passkey that you can print, or backup, or import into whatever replaces Bitwarden.
