Elon Musk launched the XChat app, a stand-alone messaging service for X users, claiming it to be the only secure, encrypted messaging app. Critics have raised concerns about XChat's security, particularly its requirement to link an existing X account and the storage of cryptographic keys on X's servers. The app's rollout faced delays and confusion, with users in the UK experiencing access issues. Initial user experiences indicated limited messaging capabilities, as many contacts may not have X accounts. The app's privacy claims were questioned, as it still collects data linked to users. XChat shares similarities with Facebook's Messenger, both requiring account creation and linking to their respective platforms.
