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.
Key Features
Decrease your risk of account compromises and identity theft, along with the consequences of lost time, money, and privacy
Use a smartphone or tablet app, hardware token, or USB security key to confirm your login requests
Get alerted if your password is stolen or guessed as soon as someone tries to log in
Choose to let Two-Step Login
trust your browser for 24 hours
(for most login requests)
Who Can Use Two-Step Login
Two-Step Login accounts are available to all current students, faculty, staff, alumni, retirees, sponsored ID holders, and affiliates.
People who have
GuestIDs
are not eligible for Two-Step Login.
