The TAN is a six-digit code consisting of letters and/or numbers. The TAN is displayed to you in the AUTHADA app after your ID card has been read with the AUTHADA app and you have successfully identified yourself.
Enter the TAN in the corresponding input field on the website of the service provider for which you want to identify yourself. Please note: To generate a TAN, it is necessary to complete the identification process and not to refresh the provider’s website during this process. For security reasons, a TAN is only valid for a limited time. Please identify yourself again if you need a new TAN.
