Your University Network ID (UNI) gives you access to your courses via the myTC Portal, as well as access to library resources and other College and University assets.


After you have been admitted and paid your tuition deposit, you will need to activate your UNI. To do so, visit the Columbia University Information Technology Manage My UNI page and click Activate My UNI or LionMail Account. Enter the requested information and create a password that meets the requirements. 


The myTC portal is a customizable, interactive web portal that acts as the “door” to TC G Suite and the Message Center, as well as other resources. TC G Suite includes your TC Gmail account. The portal comes with a variety of “information channels” such as College and course announcements, news, links to courses, the Student Information System and search engines. 

To access myTC go to, enter your UNI and password. If you need to activate your UNI or change your password, go to the Columbia University Information Technology Manage My UNI page and click Activate My UNI or LionMail Account.

TC Gmail is the official College email system. To access your TC Gmail, log into the myTC Portal and click on the Gmail icon on the upper right. The first time you use your TC Gmail, you will need to accept the terms and conditions. Next, close the browser, reopen it, click on the Gmail icon again, and you will open a window or tab with your TC Gmail account.

TC alumni keep their TC Gmail account for life. If you do not register again and do not graduate, your TC Gmail account stays active for three more semesters.

If you are also an employee, any access to employment-related email accounts or other resources is discontinued on the last day of employment for the particular office.

Follow the instructions below to add TC Gmail to your mobile device.

TC Information Technology (TCIT) provides a Student Computing Support Center (242 Horace Mann Hall) with 70 PCs and Macs, scanners and printers, two micro-computer-equipped classrooms (345 Macy), the Instructional Media Lab (265 Macy), the TV video studio, and webinar studio (345 Macy).

Printing is available in the computer labs, library, and the 10th floor of Whittier Hall. Students are provided with a quota of 20 free double-sided pages per week that can be used throughout the semester with the ability to purchase extended printing at very low cost.


TC uses Canvas as its learning management system. This system allows you to access information about your courses including syllabi, course materials, announcements, and online discussions. The classes in which you are enrolled are automatically listed in Canvas.

To access your courses in Canvas, click on the Courses tab in the myTC portal and click on Canvas. Once in Canvas, you have access to the courses you are taking or teaching.

Teachers College uses TC Gmail as the preferred way of communicating important and official information with its students. Students are required to activate their Columbia University Network ID (UNI) which includes access to the myTC portal and a TC Gmail account.

Students are responsible for being aware of official messages sent to that account. Teachers College expects that every student will receive email at this College Gmail address and will read email on a frequent and consistent basis. A student’s failure to receive and read College communications in a timely manner does not absolve that student from knowing and complying with the content of such communications.

All use of email must be consistent with all Teachers College and Columbia University policies. In particular, see TC policy on Acceptable Use and CU Policy on Acceptable Usage of Information Resources.

Access to the Internet is available throughout campus via both wired and wireless means. There are public workstations in labs, the library, and Everett Lounge.


The Message Center is accessed through myTC and gives you a customizable list of announcements and classifieds for the TC Community. By clicking on “Preferences” at the bottom of the Message Center panel, you can customize how you receive notification of the different categories of messages. If you choose to customize your settings in this way, you will receive a weekly summary of activities as well as various official announcements.

Email lists are maintained for all currently registered students for announcements from College administration and the Student Senate. There are also lists for each major, and you will receive news from your program through the lists. If you join a student organization, you may be placed on that organization’s list. Reading these announcements will keep you current with upcoming events as well as important deadlines.

Each unit in student residences has an Ethernet jack. Any resident student with a personal computer (PC/Mac) that meets the required minimum configurations including ongoing anti-virus and operating system updating can connect to the Internet at high-speed, and access resources like Email and the Internet. You will find more information on using your computer on the College network at In particular, you should follow the suggestions outlined in the following Computer Security paragraph.

Site-licensed software such as NVivo, SPSS, Qualtrics, and Endnote are available to you without charge. To access the tools, visit and click on “Software and Tools” in the TC bookmarks channel. For a complete list of software available to you, visit the TCIT Available Software page.


Active Students or Alumni who are employees who are terminated for cause will have their TC Gmail account disabled and have a replacement UNI generated with a new TC Gmail account.  Arrangements can be made in coordination with the employee’s former supervisor and HR for any request to retrieve personal information from a disabled account.


Academic Technology Services holds a series of free technology training workshops each semester. Information regarding schedules is available on our Workshops and Training page.
