Operations include transmitting, on behalf of a first application, a first request to a first service provider, the first request requesting first services from the first service provider, intercepting, at a local agent, a first redirect message from the first service provider to an identity provider, receiving an identity provider cookie from the identity provider based on a validation of credentials during the authentication process, storing a copy of the identity provider cookie, transmitting, on behalf of a second application, a second request to a second service provider, the second request requesting second services from the second service provider, intercepting a second redirect message from the second service provider to the identity provider, adding the identity provider cookie to the second redirect message, and receiving validation to access the second service provider from the identity provider based on the identity provider cookie stored by the local agent.

Per-device single sign-on across applications

This disclosure describes techniques for dynamically changing a user authorization with a service provider during an ongoing user session. The changing user authorization may be used to address changing confidence in an identity of a user consuming a service provided by the service provider. The changing user authorization may also be used to adjust a scope of a service to which a user has access. The present techniques may allow single-sign-on type protocols to accomplish the flexible and dynamic change-of-authorization functionality of some traditional protocols to handle ongoing client-server sessions, rather than simply revoking authorization for access to the service. For this reason, the present techniques are able to integrate advantages of traditional protocols with newer, single-sign-on-type protocols.
