X is urging users with security keys for two-factor authentication to re-enroll their keys by November 10, 2025, to avoid account lockouts and to facilitate the transition from the twitter.com domain to x.com, with re-enrollment required only for security key users, not those using other 2FA methods.
The iOS 16.6 beta includes the iMessage Contact Key Verification feature, which is designed for users facing digital threats. The feature lets Apple device owners verify that they are messaging with the intended person and not a malicious entity. It is not yet clear if the feature is functional in the first beta, and it may require additional settings to be enabled. Apple announced that the feature would be available on the iPhone and other Apple devices in 2023.
