X, formerly known as Twitter, has introduced Chat, an enhanced encrypted direct messaging service that now incorporates video and voice calls, disappearing messages, and file-sharing capabilities. This upgraded platform was recently announced and is currently accessible on iOS and the web, with an Android version expected to launch soon.
Chat by X boasts end-to-end encryption (E2EE) for messages and files, although message metadata, such as recipient details and timestamps, is not covered by this encryption. X acknowledges the vulnerability to potential man-in-the-middle attacks and emphasizes the need for enhanced verification methods to ensure message authenticity and device integrity in the future.
The privacy-oriented features of Chat include self-destructing messages, customizable to automatically delete after a specified time period, along with options for notifying users about screenshots or preventing screenshots entirely. Users can also edit and delete messages, make voice and video calls, and anticipate voice notes in forthcoming updates.
X initially introduced encrypted direct messages in 2023 and temporarily paused the feature for enhancements earlier this year. The relaunch as Chat signifies X’s commitment to enhancing user privacy and security within its messaging platform.
