Disclosed are an identity authentication method, terminal device and system, the method comprising the following steps: a terminal device scans a two-dimensional code after receiving a two-dimensional code scanning instruction (101); after receiving the two-dimensional code scanning instruction, the terminal device automatically opens a biological characteristic information acquisition function, and acquires the biological characteristic information of a user currently operating the terminal device (102); and conducting identity authentication on the biological characteristic information, and determining whether the user has an operation privilege corresponding to the two-dimensional code (103). The terminal executes the two-dimensional code scanning instruction to obtain a two-dimensional code, and acquires the biological characteristic information of the user currently operating the terminal device after automatically opening the biological characteristic information acquisition function, that is, the terminal can automatically acquire information for authenticating a user identity, thus reducing the steps of the user in re-entering a verification code or a password, realizing a one-button operation, reducing the operation steps of identity authentication, and improving the efficiency of the identity authentication. |
