# Logging into Mediathread

If a Mediathread site is connected to a Columbia University course, instructors and students associated with that course through the CU registrar will be able to sign in with their UNIs at [https://mediathread.ctl.columbia.edu](http://mediathread.ctl.columbia.edu/).

If you are signing in with a UNI, make sure you click the gray “Log in with Columbia UNI” button; do not enter your UNI in the “All Other Users” fields. Persons who are members of more than one Mediathread site will be prompted to select one after logging in.

Persons who do not have a Columbia UNI may be connected to Mediathread sites by creating a guest account. On the home screen, click "[Need a guest account?](https://mediathread.ctl.columbia.edu/accounts/register/)" in the login area.  Fill out form details and click "Sign Up".

To ask questions and report problems with logging in, please contact support [here](https://mediathread.ctl.columbia.edu/contact/).
