Two-Step Login

In This Article

Two-Factor Authentication

Two-Step Login adds an extra layer of security to your Cornell NetID and password by requiring:

  • something you know (your NetID and your password), plus
  • something you have (a physical device, like your phone)

This is called two-factor authentication, and it's required for access to many university services, such as Workday, Student Center, and Student Essentials. Duo Security provides the technology behind Two-Step Login. Two-Step Login makes it much more difficult for intruders to use your identity to access campus services. Even if your password has been stolen, the second step to the login process will prevent someone from logging in.

For many university services and information, particularly those that grant access to sensitive information, you will be required to use Two-Step Login.
