# Class JMXPrincipal

java.lang.Object
javax.management.remote.JMXPrincipal

All Implemented Interfaces:
  `Serializable`, `Principal`

public class JMXPrincipal extends Object implements Principal, Serializable

The identity of a remote client of the JMX Remote API.

Principals such as this `JMXPrincipal` may be associated with a particular `Subject` to augment that `Subject` with an additional identity. Refer to the `Subject` class for more information on how to achieve this. Authorization decisions can then be based upon the Principals associated with a `Subject`.
