Important

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.
