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 Identity Management system and configure an authenticator app.

It is necessary to delete old configuration files, preferably before you import a new one. To do this, go to the following two folders and, if available, delete all configuration files:
- 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:“.)
