UMIACS provides local support for a trusted on premise messaging platform using Mattermost.
This is an on-prem solution integrated into our GitLab authentication system with its MFA requirement. When signing in it will prompt you to use GitLab to login and if you haven't already then log in with the UMIACS Single Single Sign On.
You will be presented with which Teams you would like to join by default and you can select the UMIACS Team. Faculty, Labs and Centers may request a private Team for their research groups, labs or centers by sending an email to firstname.lastname@example.org.
