Abstract
This specification provides techniques for secure authentication. One example method includes receiving a login request from a computing device, wherein the login request includes a variable apparatus identifier (ID) associated with the computing device; in response to receiving the login request, determining that the variable apparatus ID corresponds to a user account; in response to determining that the variable apparatus ID corresponds to a user account, determining that an update of the variable apparatus ID is requested based on a timestamp included in the variable apparatus ID and a current time; in response to determining that the update of the variable apparatus ID is requested, generating an updated variable apparatus ID associated with the computing device; and transmitting an account login permission instruction and the updated variable apparatus ID to the computing device.
