The invention further discloses computer equipment and a computer readable storage medium. According to the method disclosed by the invention, after the client successfully accesses the network for the first time of authentication, circular authentication is carried out, and if the environment of the client is not in a trusted state or the username password is damaged, the client is disconnected.
