[keycloak-user] Passing information from custom Authenticator to a Token

[Thomas Darimont]

Hello group,

I need to pass some information form a custom Authenticator to the
IDToken/AccessToken.
One way I found to do that is by using UserSessionNotes and a "User Session
Note"
Protocol Mapper defined in a client template which is shared by all clients.

public void authenticate(AuthenticationFlowContext context) {
   ...

 context.getClientSession().getUserSessionNotes().put("someKey","someValue");
   ...
}

is this the intended way to do this sort of things?

Cheers,
Thomas
