Sometimes when you try to access Box pages from within your Box account or otherwise you may be prompted to login from a Box screen rather than the standard University of Minnesota login page. Single Sign On (SSO) is how University accounts access Box.
You will be brought to what looks like a login screen. DO NOT put in your username and password. Click on the link below the Authorize button that says Use Single Sign On (SSO). The Password area goes away.
Enter your full email in the Email Address area (system campuses should be using @umn.edu as well) and click Authorize.
Note: Depending on your current authentication status you may get another push from Duo
After either clicking Authorize or accepting your Duo Authentication you will be at the Box page you were attempting to access.
