Methods, Apparatuses, and Computer Program Products for Providing a Single Service Sign-On

An apparatus may include a processor configured to receive a request for an access token from a remote entity, wherein the request includes an indication of a requested service. The processor may be further configured to determine a request type, wherein the request type may be a user identification and password combination, a request token exchange, or an access token exchange. The processor may be additionally configured to extract one or more parameters included in the request based upon the determined request type and to perform one or more security checks based at least in part upon the one or more extracted parameters. The processor may be further configured to create an access token based at least in part upon the results of the one or more security checks and to provide the access token to the remote entity.
