Effective immediately, VPN access now supports **authentication with your LoginID and a time-based one-time password (TOTP)**.

Password-based authentication will remain available until September 30th, 2026. Beginning October 1st, 2026, VPN access will be available exclusively with your LoginID and a TOTP code.

To use TOTP, you must enable two-factor authentication (2FA) for your RUB account in the **[[http://rub.de/login|Identity Management system]]** and configure an **[[https://www.it-services.ruhr-uni-bochum.de/services/ias/2fa.html.de|authenticator app]]**.

If you cannot download the configuration file or if it is displayed directly in the browser window, you can download it via the context menu (opens by right-clicking on the download link) and then via "Save target as". Some browser does not offer this option. In this case you will have to use a different browser.

  * C:\Users\*USERNAME*\OpenVPN\config (Please make sure that you select the user name that has administrative rights.)
  * C:\Program Files\OpenVPN\config (Select the hard disk on which you have installed OpenVPN, it does not necessarily have to be called "C:".)

Then import the current configuration file again via the context menu (right-click on the OpenVPN icon on the right in the system tray) via //Import//.
