Abstract: A method for use by a system computer for granting access to a network resource includes receiving, in a first session, a first request for accessing the network resource, the first request including authorization information of a user of an access computer, initiating, while in the first session and using the first authorization information, a first authorization process with one or more authorization computers, and determining a failure relating to the first authorization process initiated with the one or more authorization computers. The method further includes, upon determining the failure, sending a second request indicating a temporary access token is to be delivered to the access computer in response to an access computer executing a session refresh for initiating a second session.
