UMA 2.0 is known as a delegation of authorizations standard. Keycloak is fully compatible with UMA 2.0.
With a bash tool developped by please-open.it, let’s see how to use UMA 2.0

Actions tokens are a particular type of token that allows unauthenticated users to perform some limited and predefined actions.
In this article we will see how to use them to create authenticated download links with a simple and short PHP script intended to run on shared web hosting.
