Security Keys for Apple ID is an optional advanced security feature designed for added protection from phishing, social engineering scams and many other cyberattacks. Security keys strengthens the two-factor authentication process and help prevent your second authentication factor from being intercepted or requested by an attacker. The idea is that even if a hacker does know your password, they can’t access your account without also having access to the physical key.
Note: You’ll need a minimum of two NFC Security Keys in case you lose or misplace one.
