A new online support article has been published detailing the newly released Security Key feature.
Security Key for Apple ID was released with iOS 16.3, macOS 13.2 and iPadOS 16.3. This article provides useful tips on how users can utilize security keys to protect their devices and data from unwanted objects.
Apple reiterates that Security Key is for those seeking additional protection from social engineering scams and phishing attacks through two-factor authentication that uses a FIDO-certified security key and enters a password instead of the usual six-digit code on other owned devices. However, users should be careful not to lose the security key, as it can permanently lock the Apple ID account. To prevent this, users are advised to set up two security keys as backups.
Apple also recommended keeping your keys in more than one place, such as at home and at work. The security key can be enabled in Settings and Passwords & Security.
