Install the correct client for your device, register with your phone number, enter the verification code, and verify the people you communicate with before sharing sensitive information.

Messages, groups, calls, and linked devices

MATRIX CHAT clients are planned to support familiar secure-messaging workflows. Feature availability may differ during private beta, so check the release notes before relying on a specific client feature.

How MATRIX CHAT protects conversations

Message content is designed around Signal Protocol end-to-end encryption. MATRIX CHAT stores selected short-lived server data on active RAM disk so it does not become routine persistent storage. Verify safety information out of band for high-risk conversations.

Registration or connection problems

Confirm internet access, the correct phone-number format, SMS availability, correct system time, and the latest client version. Restart the client before re-registering. Do not repeatedly request verification codes, because rate limits may temporarily delay another attempt.

Changing or replacing a device

Treat a new device as a new trust event. Re-check linked devices, verify important contacts again, and remove access from hardware you no longer control. Never share registration codes or recovery material with support staff.
