Embodiments of the present disclosure relate to methods, systems and computer program products for authorization of resource access. According to the method, a first token is assigned by one or more processing units to authorize a client to access at least one protected resource of a resource owner. The first token depends on an access session with the client. A second token associated with at least one long-term protected resource of the resource owner is assigned by one or more processing units to the client based on the assigning of the first token. The second token is independent from the access session. In response to receiving a request including the second token from the client, the at least one long-term protected resource is provided by one or more processing units to the client. In other embodiments, a further method and corresponding systems and computer program products are disclosed.
