[keycloak-user] obtaining token when using identify broker

Apologies again if this was already answered, but my subscription to the ML keeps getting cut and there is no archive to check! How can I obtain a token in the following scenario: 1. My keycloak realm is set up to manage users with identity brokering (e.g. in a browser they would login through GitHub, Google etc.) 2. I have a public client in that realm that has REST API that requires access to be authenticated 3. I want to access that API using curl or other CLI tool so need to provide an access token. How can I get a token? Thanks Tim
