Passwords have problems, but less than putting all authentication secrets in a single basket or ecosystem is (which is what big tech fundamentally wants).
Passkeys are a solution to a manufactured problem, and keeps getting pushed because it is a useful big tech honey trap that solidifies their user's captivity in their ecosystems.
WebAuthn? No, thanks.
It’s one more brick in the wall preventing general-purpose computing. Want to authenticate to Banana Computers? Well, you have to use one of their oDevices, because they will not let you use a RoboPhone to store your passkeys.
