2. Single Sign-On, Webauth, and Nexus - what does it all mean?
Despite the many names you might hear being used, things are really quite simple. Your Oxford username and password can be used to login to Webauth – this will start a Single Sign-On session to avoid you having to re-enter your details. The same Oxford username and password are used to login to Nexus (over the web or using a desktop client).

You can think of Webauth as a central authentication system that is trusted by various services in Oxford to handle all the username and password checking so that each individual service doesn't need to do it for itself. It is highly secure and very convenient as you only need to enter your username and password once in order to visit multiple independent web services. To end your Single Sign-On session ("logout") you will need to close your web browser (that includes quitting all running copies of your web browser.
