Setting up Duo Mobile MFA

Multi-Factor Authentication (MFA) adds a second layer of security to your SJSUOne account by verifying your identity using a second factor provided through the free Duo Mobile app. Duo can prevent someone from logging into your account, even if they know your password. To activate Duo MFA for your SJSUOne account you will need to scan a QR code on a screen using your phone. You will need two devices to complete this process.

  1. Install the Duo Mobile app on your phone or tablet
  2. Set up your SJSU account, using your computer or a second mobile device. The first time you log in to one.SJSU, a series of prompts will guide you through the self-service Duo Mobile MFA enrollment process.
  3. Set up Duo Restore to make it easy to move to a new mobile phone in the future

You will need to install Duo Mobile on one device, and sign in to on another device.

Set up Duo Mobile on your Smartphone

Note: If you do not have a smartphone or do not want to install DUO on your phone, you may contact the IT Service Desk (408-924-1530) to request a hardware token (key fob). Requesting a key fob will take more time than the self-service Duo Mobile app activation process.

The secondary email should match the email you used when you applied. If you need to update your secondary email, you must first complete all OKTA steps.

Click “Create Account.” You will be able to access MySJSU.

For instructions on changing  your secondary email, see Set My Preferred Email Address.

Congratulations! You are now enrolled in DUO two-factor authentication and your SJSUOne ID account is fully activated.

Setup recovery with Duo Restore

If you have an iPhone or iPad, Duo uses iCloud Backup and iCloud Keychain to back up your Duo Mobile app and restore it when you set up a new phone🔗. Please ensure your phone is backing up to iCloud so you can restore to a new phone without losing your Duo Mobile.

Android phones and tablets need to enable Duo Restore in the Duo Mobile app🔗. When choosing a Google Account to back up to, choose the personal Google Account you used to activate your phone when you purchased it. When installing on a new phone set up with the same personal Google Account, you can choose to restore your Duo settings from that account.
