Passkeys, the popular name for FIDO, are not only easy, they offer better protection against phishing than other forms of multi-factor authentication. This is how they work.

What is a passkey? A passkey is a new way to sign in that works completely without passwords. By using the security capabilities of your devices like Touch ID and Face ID, passkeys are way more secure and are easier to use than both passwords and all current 2-factor authentication methods.
