Disclosed are various embodiments for delegating security authorization to at least one application executed on a client device. A computing device is employed to send to a remote server, from an agent application, a request for a first access credential. The first access credential is received from the remote server and a determination is made by the agent application in communication with a managed application, that the managed application requires a second access credential. In response to the determination being made that the managed application requires the second access credential, the second access credential is sent to the managed application, from the agent application. An indication that the agent is authorized to be in communication with managed applications regarding a need for access credentials is stored and the agent application determines where at least one of the managed applications requires an access credential.
