What is it?
Duo is a multi-factor authentication tool used by MHC systems that leverages a mobile app to be the "second step" when you're logging in.
Users whose phones are not compatible with the Duo Mobile app may request an alternate method of completing Duo 2-step verification.
Alternate methods include:
- SMS codes (students)
- Duo hardware tokens (faculty/staff)

Who can use it?
MHC faculty or staff whose phones are not compatible with the Duo Mobile app (or who don't want to use their personal phone for Duo) can request a hardware token.
Students whose phones are not compatible with the Duo Mobile app can request to be able to complete Duo verification via SMS-delivered codes instead.
How do I get it?
- Please visit duo.mtholyoke.edu and select Log in to set up or verify Duo and log in on the blue and white MHC login screen as you would normally.
- After you enter your credentials, your account has been created in Duo. Do not proceed with NEXT, close the window and you can submit this form to request a hardware token
- Use the "Request alternate Duo method" button on this page.
Hours/Availability
Requests are processed during regular business hours when the College is open.
