Article Body

What is Phishing-Resistant Multifactor Authentication (MFA)?

Phishing-resistant MFA provides additional protection for your Penn State Account by using sign-in methods that are designed to prevent phishing attacks. While traditional MFA methods, such as Microsoft Authenticator push notifications and number matching provide strong account security, they still rely on a password and are not considered phishing-resistant.

What are Passkeys?

Passkeys are a phishing-resistant technology that replace your password. They cannot be easily stolen or entered into a fraudulent website like a password can. Passkeys can be stored in several ways, including on your smartphone, computer, password manager, or a physical FIDO2 security key.

Once enrolled, you will no longer use your password to authenticate. Instead, you will verify your identity by using a PIN or biometrics (like Face ID or Touch ID) directly on your device, tapping your physical FIDO2 security key, or scanning a QR code with your phone and using your phone's unlock method to complete sign-in.
