A safe password or an insecure but convenient passkey, an easy choice for a noob user. I avoid passkeys like a plague.



By definition, simpler = less secure.

Please explain how a passkey is less secure than a password.

Why is it impossible for something to be secure and simple?

With a passkey the private key used to generate the challenge never leaves the passkey and the challenge can't be used in a replay attack. Someone gets your password and it's game over.
