In my latest hands-on video, I take an in-depth look at what it’s like to use hardware security keys in iOS 16.3. Hardware security keys are direct replacements for the six digit verification codes sent to trusted iOS devices. Hardware security keys act like trusted devices, and must be used as the second form of authentication alongside your username and password combo.
Video walkthrough: iOS 16.3
Apple makes users who wish to use hardware security keys set up two keys initially. This is a requirement so that you will be able to access your account in case one of the keys is damaged or lost. Two keys is the bare minimum, but you can add even more than that if you want. I used a pair of inexpensive FIDO2-compatible security keys that I purchased from Amazon.
If you lose all of your keys, you will be locked out of your account, and Apple will not be able to assist you. That is among one of the reasons why most people should stick to 6-digit verification codes. That being said, hardware security keys increase security by eliminating the possibility of advanced verification code phishing attacks. If you’re a high profile target, these physical keys may be a good option to harden your security.
I also discuss other iOS 16.3 features in this video, and revisit some 16.2 features as well, such as Live Activity’s new more frequent updates setting, and logging into iCloud with Advance Data Protection enabled. I’ll have more on these features in a future post.
