Techniques for a server-based reconnection of disconnected devices in a network are described. In an example, a computer system receives, from a second device, first data of a first device. The first data indicates that the first device has disconnected from the network due a change in the password of the network. The computer system determines that the first device is authorized to connect to the network. Based on the first device being authorized, the computer system transmits a request for a token. The computer system compares the token to a token stored by the computer system. In response to the tokens matching, the computer system transmits second data to the first device via the second device. The second data includes an updated password of the network. The first device uses the second data to reestablish a connection with the network.
