In one embodiment, a method includes detecting interception of data sent by the computing device to a first network resource through a communication network. The first network resource corresponds to a particular domain of the communication network. The method also includes determining whether the communication network is administered by the particular domain; and automatically generating a request to access the communication network that identifies a second network resource based at least in part on the determination. The second network resource is configured to authenticate a user to the particular domain of the communication network. The method also includes sending the request to the second network resource to access the communication network.
