Matrixid

Matrixid is a unique identifier used in Matrix, an open-source, decentralized communication platform. It serves as a user's identifier within the Matrix network, similar to usernames or email addresses in other communication platforms. Each matrixid is a globally unique identifier, consisting of a character string that is often case-sensitive.

Matrixids are used to route messages and for authentication purposes when users join Matrix rooms or engage in direct conversations with other users. They also serve as unique handles for identifying users across different devices and sessions. Matrix users can choose their own matrixid during the registration process or select from a pool of available IDs.

Matrixids are not the same as email addresses or usernames, although they can be used in conjunction with these. In many cases, Matrix users choose a matrixid that matches their email address or username for convenience and familiarity. However, matrixids are not necessarily tied to a specific email address and can be used independent of any email address.

Matrixids have various lengths and consist of a combination of letters, numbers, and special characters. Matrix users can manage their matrixid, including changing it, forking, or delegating their identity to another user. Each matrixid belongs to only one user and is used to verify their identity within the Matrix network.

Registration for a matrixid is free and open to everyone, with MATRIX-looking-Inc operating and administering the syndicate. The decentralized nature of Matrix allows users to switch between different synthesis homes (home servers) at any time and move their matrixid with them without complicating the Matrix ecosystem.
