Apple has stated that the complete iMessage contact key verification functionality will be available on iPhones and other Apple devices in 2023, making it one of the anticipated highlights of iOS 16.

With the release of the fourth betas, Apple continues to refine its software updates and incorporate valuable feedback from developers. These iterative releases pave the way for a more polished and secure user experience, ensuring that Apple’s ecosystem remains at the forefront of innovation and user protection.
