Apple has been focusing on security for a few years now, and the release of iOS 17.2 comes with all-new features. Contact Key Verification (CKV) is a new iMessage setting that lets you be sure the person you’re sending a message to is who you think they are.
Simply put, this feature is designed to prevent unwanted people from participating in private conversations. Are they simply spying on what’s going on, or are they actively trying to trick you into thinking they’re someone else? You don’t have to worry too much about it, but it’s here to give you peace of mind.
Here’s how to enable iMessage contact key validation in iOS 17.2.
Contact Key Verification is an opt-in setting in iMessage designed to provide automatic alerts when an unverified device is detected. The idea here is that when you set up contact key verification on your iMessage account, each device has its own public verification key.
This warning appears when an unrecognized device suddenly appears in your iMessage account. This suggests that someone has snuck into the conversation in a way that would normally go undetected.
Apple clarified that this type of attack has never occurred before. In short, CKV is an example of Apple being proactive about security measures rather than playing catch-up with malicious actors who actively exploit security holes.
CKV is not a particularly useful feature for the average person. You’re not interested enough to justify the effort required to circumvent Apple’s existing security measures. Instead, it targets common targets such as politicians, journalists, and human rights activists.
There are no disadvantages to enabling contact key validation. When it comes to private messages, you can never be too secure.
Note: This feature only works on iPhones running iOS 17.2 or later.
