If you lose all of your trusted devices and security keys, you could be locked out of your account permanently. You're responsible for maintaining access to your security keys. A security key can act as the second piece of information, instead of the six-digit verification code that is normally used.īecause you use a physical key instead of the six-digit code, security keys strengthen the two-factor authentication process and help prevent your second authentication factor from being intercepted or requested by an attacker.The FIPS validated devices have just been tested against the FIPS 140 requirements developed by NIST. As for FIPS, it is a US Federal Government 'certification' or validation of the cryptographic algorithms. The first piece of information is your Apple ID password. The YubiKey 5 Series keys (both FIPS and non-FIPS) are the latest YubiKey authentication devices.With two-factor authentication - which is designed to make sure that you're the only one who can access your Apple ID account - you need to provide two pieces of information to sign in with your Apple ID to a new device or on the web. Security Keys for Apple ID is an optional advanced security feature designed for people who want extra protection from targeted attacks, such as phishing or social engineering scams.
