@Gargron ah yes, there are still some use cases for shared passwords… good point.
However… today I learned a bit about how one’s password manager can act as the “authenticator” mechanism. So with your passkey synced via your password manager, you can still login from different devices.
Anyway I already use shared passwords AND shared TOTP codes all synced through the password manager. Works super well.
So if passkeys sync as painlessly then I will be more open to them. Will have to test!
