As of Mar. 13, 2018...
UVA students are now required to enroll in 2-Step Login to add an extra layer of security to their computing accounts. Enrollment is mandatory by April 16, 2018.
There is an addition to the NetBadge screen because of this:
NetBadge is the gatekeeper when a website, service, or application at the University of Virginia needs to know and verify your identity before granting you access. NetBadge is not an ITS computing account.
Important NetBadge Security Reminder: Always verify that you are on the real UVA NetBadge page first at https://netbadge.virginia.edu.
