A two-dimensional code generated from encrypted original authentication data can be displayed on an authentication device. The code is read and decrypted by an authentication application on a mobile device. This can generate and display a new two-dimensional code. The new code can contain additional information, and the new two-dimensional code is read by the two-dimensional code reading unit of an authentication device. It is then authenticated.
