Passcode via text message is only available upon request and is not the preferred 2FA authentication method because of the increase in SIM card swap scam.
Before you get started, if you are already signed-in to Passport York and/or enabled the "Yes, this is my device" setting, access https://mms.yorku.ca in Incognito or Private mode.
Step 1: At the Duo prompt, please click on "Other options".
Step 2: Select "Text message passcode*".
Step 3: A one-time passcode is sent to your registered phone number via SMS text messaging. Enter the passcode and click on "Verify". Please be advised that the one-time passcode cannot be re-used.
Step 4: You will be prompted with a "Is this your device?" screen. To reduce how often 2FA is required on a particular trusted device, you can click on "Yes, this is my device" which will remember the device for 30 days. If this is a shared device or not your own device, please select "No, other people use this device".
