<p>Systems and methods are provided for login and authorization. For example, a third- party terminal receives a login request from a user and sends an authorization request from the third-party terminal to a network server; the network server generates first two- dimensional-barcode information and sends the first two-dimensional-barcode information to the third-party terminal; the third-party terminal displays a first two-dimensional-barcode image; a mobile terminal extracts the first two-dimensional-barcode information from the first two-dimensional-barcode image and sends first user account information and the first two-dimensional-barcode information to the network server; the network server validates the first user account information and the first two-dimensional-barcode information based on at least information associated with stored second user account information and second two- dimensional-barcode information generated by the network server.</p> |
