Apple’s Contact Key Verification feature, introduced with iOS 17.2 in December 2023, helps users ensure their messages are secure.
This tool is especially useful for journalists, activists, and others who need to verify they are messaging the right person.
With the release of iOS 18.1, more users are discovering this powerful security option.
If prompted, update any other devices linked to your Apple ID to use this feature fully.
Once enabled, you can verify someone’s identity in two ways:
If the codes don’t match, stop messaging the person until their identity is confirmed.
This feature ensures the person you’re messaging is who they claim to be. While most users may not need this level of security, it provides peace of mind in an age of increasing digital threats.
For added protection, always keep your iPhone updated and avoid sharing sensitive information without verification.
