William Brown is back! This time Josh chats with him about Passkeys. WTF are they? A Passkey is a form of multi factor authentication, but it's not super obvious what that really means. William does a fantastic job explaining what a Passkey is, how we got to where we are today with Passkeys. He shares a ton of explanations about the whole world of authentication along the way. Some of this stuff is basically magic.
