The authenticator app "privacyIDEA Authenticator" manages one-time passwords for logging in to web applications and other services. This app is recommended and supported for secure digital login at TU Dresden. The app is multilingual, but does NOT offer a data backup option for the managed one-time passwords. If you lose your smartphone or use a new smartphone, you will need to set up a new token.

To set up a one-time password in the Self-Service-Portal as a second factor for login processes, the following steps are necessary in the app, which are shown using iOS as an example; the procedure is identical under Android:
 

  1. Call up the "privacyIDEA Authenticator" app.
