Apparatus, systems, and methods may operate to receive, at a generating identity provider (IDP), original user credentials sufficient to authenticate a user directly from a user machine, or indirectly from an initial identity provider. Additional activities may include generating, by the generating IDP, generated user credentials having the lifetime of a login session associated with the user, the lifetime initiated approximately when the original user credentials or a token associated with the user are/is validated at the generating IDP. Still further activities may include receiving a request associated with the user during the login session to access an application protected by an agent, and transmitting at least part of the generated user credentials from the generating IDP to the application to authenticate the user to the generating IDP while the login session is not terminated or expired. Additional apparatus, systems, and methods are disclosed.
