TOKEN EXCHANGE WITH CLIENT GENERATED TOKEN

A client can be authenticated with an identity provider. The identity provider can generate an identity provider token after successful authentication. Prior to issuing a request to a service provider, the client can request a temporary (one time use) token from the identity provider. The request may include a client token to verify the client's identity. The identity provider can validate the client token using details saved in the identity provider token and issue the temporary token to the client. The client can provide the temporary token to a service provider in a request for service. The service provider can validate the temporary token with the identity provider. If the temporary token is valid (i.e., has not already been used), the service provider can respond to the request. The use of a temporary token and not sharing the identity provider token with the client can prevent security breaches.
