Technology described in this document can be embodied in a method for facilitating automatic connection to a network. The method includes receiving, at a first device that is authenticated to the network, an identifier of a second device, and retrieving, by the first device based on the identifier, a public key for the second device. The data encrypted using the public key is decryptable using a private key of the second device. The method also includes encrypting, using the public key for the second device, credential information usable by the second device for authenticating to the network, and transmitting, to the second device, the encrypted credential information.
