How to Set Up and Use Security Keys for Your Apple ID on an iPhone
Security keys are physical keys that safeguard your Apple ID and all your personal data.

This ensures no one else can intercept authentication since the key is only in your possession, adding a firm layer of protection for your information. This article will discuss how you may set up and use security keys with your iPhone.
