Apple has put a lot of emphasis on security over the past few years, and the release of iOS 17.2 comes with a brand new feature. Contact Key Verification (CKV) is a new setting for iMessage, which ensures you can be certain that the person you’re messaging is who you think they are.
Simply put, the feature is designed to keep unwanted parties out of your private conversations. Whether they’re simplifying snooping on what’s going on, or actively attempting to trick you into thinking they’re someone else. It’s not something you really need to be worried about, but it is available for your own peace of mind.
Here’s how to enable iMessage’s Contact Key Verification in iOS 17.2.
Contact Key Verification is an opt-in setting for iMessage, designed to offer automatic alerts if unverified devices are detected. The idea here is that once you have Contact Key Verification set up on your iMessage account, each device has its own public verification key.
The warning comes when a device suddenly appears in an iMessage account that isn’t recognized. It suggests that someone has snuck their way into a conversation in a way that would otherwise be undetected.
Apple has made it clear that it’s never seen this kind of attack happen before. So CKV is a case of Apple being proactive with its security measures, rather than trying to catch up with bad actors that are actively exploiting security holes.
CKV is a feature that won’t be particularly useful for ordinary people. You’re just not interesting enough to warrant the amount of effort it would take to try and bypass Apple’s existing security measure. Instead this is for people who would be common targets, like politicians, journalists, human rights activists and so on.
Not that there’s any disadvantage to having Contact Key Verification enabled, There’s no such thing as too much security when it comes to private messages.
Note: this feature only works on iPhones running iOS 17.2 or later.

Your options are to either update those devices to the appropriate software, or disable iMessage on that device — in my case an iPad. Either option is fine, but you’ll need to pick one to continue.
