Since account locking and suspension are authentication API agnostic, this is a pre-requisite to adding the new OAuth 2.0-based API. This also splits the endpoints that where all included in the registration OpenAPI data, to separate them cleanly in the spec, and avoid having deactivation show before registration.

|
|
description: |-
|
|
This API endpoint uses the [User-Interactive Authentication API](/client-server-api/#user-interactive-authentication-api), except in
|
|
the cases where a guest account is being registered.
|
|
|
|
Register for an account on this homeserver.
|
|
|
|
There are two kinds of user account:
|
|
|
|
- `user` accounts. These accounts may use the full API described in this specification.
|
|
|
|
- `guest` accounts. These accounts may have limited permissions and may not be supported by all servers.
|
|
|
|
If registration is successful, this endpoint will issue an access token
|
|
the client can use to authorize itself in subsequent requests.
|
|
|
|
If the client does not supply a `device_id`, the server must
|
|
auto-generate one.
|
|
|
|
The server SHOULD register an account with a User ID based on the
|
|
`username` provided, if any. Note that the grammar of Matrix User ID
|
|
localparts is restricted, so the server MUST either map the provided
|
|
`username` onto a `user_id` in a logical manner, or reject any
|
|
`username` which does not comply to the grammar with
|
|
`M_INVALID_USERNAME`.
|
|
|
|
Matrix clients MUST NOT assume that localpart of the registered
|
|
`user_id` matches the provided `username`.
|
|
|
|
The returned access token must be associated with the `device_id`
|
|
supplied by the client or generated by the server. The server may
|
|
invalidate any access token previously associated with that device. See
|
|
[Relationship between access tokens and devices](/client-server-api/#relationship-between-access-tokens-and-devices).
|
|
|
|
When registering a guest account, all parameters in the request body
|
|
with the exception of `initial_device_display_name` MUST BE ignored
|
|
by the server. The server MUST pick a `device_id` for the account
|
|
regardless of input.
|
|
|
|
Any user ID returned by this API must conform to the grammar given in the
|
|
[Matrix specification](/appendices/#user-identifiers).

These errors may be returned at any stage of the registration process,

including after authentication if the requested user ID was registered
|

whilst the client was performing authentication.
|
|
|
|
Homeservers MUST perform the relevant checks and return these codes before

performing User-Interactive Authentication, although they may also return

|
them after authentication is completed if, for example, the requested user ID
|
|
was registered whilst the client was performing authentication.

Checks to see if a username is available, and valid, for the server.

The server should check to ensure that, at the time of the request, the

username requested is available for use. This includes verifying that an

Matrix clients may wish to use this API prior to attempting registration,
