X Chat not only adds convenient features but also introduces a mechanism that protects privacy through encryption.

With traditional DMs, encryption was available only to people subscribed to X's paid subscription service “X Premium”, but X Chat encryption is available to everyone.

X Chat encryption is a feature that internally encrypts messages between the two parties who are communicating when sending and receiving them.

When message encryption is enabled, even X's operators cannot read the contents of messages, helping protect privacy and security.

When you open X Chat for the first time after DMs are integrated into X Chat, you will be asked to set a passcode, and this passcode is used to store the key needed for encryption and decryption (returning encrypted data to its original form).
