The login process for Tk20 has changed to allow for DUO 2-factor authentication for all students, faculty, and staff. When you click on the login button you’ll be taken to an authentication page which will ask for your JMU username and password. You’ll then have to confirm the login using your mobile phone, tablet, or U2F token. For more information on 2-factor authentication see the JMU computing page.
Cooperating teachers will continue to use the old method of logging in to Tk20 which does not use DUO.
