If you did not touch the Yes, this is my device button, your session with two-step login with Duo is integrated with Rutgers’ current Single Sign-On (SSO) authentication. Generally, once logged-in with Duo, there is 8 hours of an active SSO session without the need to re-authenticate again. However, there could be some exceptions based on a web application’s session policy and web browser implementations. Also, if you close your web browser and then open a new web browser, you will be prompted to authenticate to establish a new SSO session.
