You're seeing this message because there was an issue authenticating for the service you wish to access. Most likely, you are using a bookmark or link that goes directly to the shibboleth authentication page (shibboleth2.uchicago.edu). This will not work. You should make sure you are going directly to the web page for the service you wish to access, such as my.uchicago.edu or classes.uchicago.edu; if you are going to the correct page, it will then bounce you to the shibboleth authentication page and you should be able to access that normally. Please close your browser, reopen it, and then go to the website you wish to reach.
The University of Chicago relies on a service called Shibboleth to provide login authentication to University and external web services.
Shibboleth allows users with a valid CNetID to access multiple web applications with a single sign-on. Once a user logs in to one resource, they are granted access to multiple web applications, for which they have appropriate permissions, without being prompted to log in at each. When Shibboleth is utilized to control access to external web services, the system will evaluate the user's credentials and determine if access may be granted to the secure site. Whether or not the user may be granted access to secure external services with their CNetID depends on their affiliation with the University, various permissions associated with their account, and the requirements of the external service.
You may be seeing this page because you used the Back button while browsing a secure web site or application. Alternatively, you may have mistakenly bookmarked the web login form instead of the actual web site you wanted to bookmark or used a link created by somebody else who made the same mistake.
If you have just registered for Two-Factor Authentication (2FA), please close your browser, reopen it, and then go to the website you wish to reach.
Left unchecked, this can cause errors on some browsers or result in you returning to the web site you tried to leave, so this page is presented instead.
