# account-required This specification defines the informational `soju.im/account-required` capability. If present, it indicates that the connection to the server cannot be completed unless the clients authenticates, typically via SASL. Note, the absence of this capability does not indicate that connection registration can be completed without authentication; it may be disallowed due to specific properties of the connection (e.g. an untrustworthy IP address), which will be indicated instead by `FAIL * ACCOUNT_REQUIRED`. Clients MUST NOT request `soju.im/account-required`; servers MUST reject any `CAP REQ` command including this capability.
