With our digital lives so deeply intertwined, our communications need to be secure and private.
Answering the call of user demand, Apple has developed Contact Key Verification for iMessage—a feature that provides users with an extra layer of assurance about the genuineness of their conversations.
The Importance of Verifying Contact Keys
As per 9to5Mac, this is an opt-in security feature designed to protect iMessage conversations from probable eavesdropping or man-in-the-middle attacks.
When you turn it on, you’ll automatically receive an alert if the encryption keys used in your iMessage conversation don’t match the ones expected for the intended recipient.
To put it another way, CKV serves as a security measure by alerting you when an unauthorized device is added to an iMessage account, potentially jeopardizing the confidentiality of your messages.
Increasing Security by Verification
Although Apple has not yet experienced these sophisticated attacks, the company’s adoption of CKV shows how proactive it is in preventing threats and giving users an extra layer of security.
The special feature is that enabling CKV doesn’t compromise the usability or functionality of your iPhone or iMessage.
That means that the additional security may benefit users without sacrificing convenience, if they do not necessarily have to meet the highest levels of protection.
How to Turn on Contact Key Authentication
Ensure that all of the devices logged in to your iCloud account are on iOS 17.2, macOS 14.2, or watchOS 10.2 or later, then enable CKV on your iPhone.
Temporarily sign out of iMessage on all devices still running earlier software versions.
Once all devices meet the software requirements, follow these steps:
- If your iPhone is running iOS 17.2 or later, open the Settings app.
- On the Settings menu, tap on your name at the top.
- When you get to the very bottom, scroll down and choose “Contact Key Verification.”
- Turn on the feature known as “Verification in iMessage”.
- To finish the activation process, adhere to the on-screen instructions.
With Contact Key Verification enabled, you can engage in iMessage conversations with an added level of confidence, knowing that any potential security breaches will be promptly detected and reported.
