How to Get Started Using Duo in the myTC Portal

In order to protect your confidential direct deposit banking information, all Teachers College faculty and staff will be required to use Multi-Factor Authentication (MFA) to access their online, self-service direct deposit banking information on the myTC Portal. MFA provides a secure avenue for TC employees to access direct deposit information from both on and off campus.

Teachers College has selected Duo as the MFA service to verify your identity for the myTC Portal.
