public Object getPrincipal()
Description copied from interface: Authentication
The identity of the principal being authenticated. In the case of an authentication request with username and password, this would be the username. Callers are expected to populate the principal for an authentication request.

The AuthenticationManager implementation will often return an Authentication containing richer information as the principal for use by the application. Many of the authentication providers will create a UserDetails object as the principal.

Specified by:
getPrincipal in interface Authentication
the Principal being authenticated or the authenticated principal after authentication.
