Typically, this means you've been logged out of our filter, Securly. This login process usually happens automatically because it's tied to our Office 365 accounts, but sometimes it needs a jumpstart.
1) Log in to Classlink (launchpad.classlink.com/maryville)
2) Click on the appropriate Securly login icon - either Securly Student Login or Securly Staff Login
3) It will walk you through logging in to your Office 365 account. If it prompts for "Work or School Account" or "Personal" account, choose "Work or School"
4) If you see Wikipedia pop up, it worked!
5) If you continue to have access trouble, open a support ticket with your school.
