How To Do Contact Key Verification In iMessage?

To perform Contact Key Verification in iMessage on an iPhone, follow these steps:

1. Ensure your device meets the minimum software requirement: iOS 17.2 or later, along with iCloud and iMessage enabled with the same Apple ID, and two-factor authentication turned on for your Apple ID.

2. Enable Contact Key Verification:

   • Go to Settings > [your name] > Contact Key Verification.
   • Turn on Verification in iMessage, then tap Continue.

3. Manually verify contacts:

   • Open Messages and select a conversation.
   • Tap the contact's name to view Conversation Details.
   • Tap "Verify Contact" for both you and the other person to generate a code.
   • Compare the codes on both devices to verify. If the codes match, you've successfully verified the contact.

4. Share your Public Verification Code:

   • Go to Settings > [your name] > Contact Key Verification.
   • Tap Show Public Verification Code to display your code.
   • Share your code with others directly or post it online for others to use.

5. Mark a contact as verified with their Public Verification Code:

   • At the top of the iMessage conversation, select the person's name.
   • Select Info, then Edit.
   • Type or paste the Public Verification Code shared by the contact into the verification code field. If the codes match, tap Mark as Verified to add the code to the contact card.

6. Check the verification status:

   • View the presence of a checkmark beside the name in Messages to confirm successful verification.
   • Look up the verification details in Conversation Details or find the Public Verification Code within the contact's info in Contacts app.

These steps assume iOS 17.2 or later versions. Ensure your devices meet the software requirement before proceeding with Contact Key Verification.
