[keycloak-dev] configure longer access tokens / permanent access tokens

Dear All, to better support IoT devices, we are looking to support longer expiration for specific tokens (when using a specific scope - in a similar way to offline_access scope). We have been looking into: https://github.com/looorent/keycloak-configurable-token-api The issue is that, while using this plugin it is possible to extend the life of a token, the underlying session will anyhow expire based on the max duration of token lifespan, so if you validate the token after the session expiration, the validation will say that the token is not active. What could be a non intrusive way to support extending the life of specific sessions associated to such tokens? (i.e. without making changes to the core code). We thought about changing the started value in the session an put it in the future, but this is not actually possible. Only getStarted is available on UserSessions. An other alternative would be to set a very long token lifespan for the client , but the all tokens will have such long life (which is not what we aim for). Any feedback / idea is welcome :) Cheers, Federico
