What is Two-Factor Authentication?

Two-Factor Authentication (2FA) adds a second layer of security to your SJSUOne account. By verifying your identity using a second factor (such as your mobile device or a key fob), 2FA prevents anyone else from logging into your account, even if they know your password.

Duo 2FA only effects your SJSUOne account. Once it is set up, you must use Duo 2FA to sign-in to this account and its associated services (SJSU Email, PeopleSoft, CFS, FTS, etc). It does not apply to your MLML-specific credentials.

Currently, it is available to all SJSU/Foundation Staff, Faculty, and Student Employees. 


To setup Duo 2-Factor Authentication:


First Steps:

  • Go to the SJSU Duo Page
  • Scroll down to Register for Duo 2FA - SJSU Employees Only
  • Select the Smartphone App option in the Duo Method section of the form.
    • Please Note: Only select the Key Fob option if you do not own a smartphone or absolutely refuse to install the Duo App on your phone. A key fob is a small physical device that displays a continuously updating passcode. Please submit an MLML IT Helpdesk Ticket to request a key fob.
  • Enter your information and then Submit the form. Select “College of Science” in the Division or College section:
  • Wait to receive an email from SJSU IT enabling Duo on your account
