Audience: Purdue faculty, staff, and students
Purpose: Help users understand VPN login changes and configure MFA correctly
What’s Changing?
Purdue is switching from Duo to Microsoft Authenticator for VPN access. This affects how you verify your identity when logging into VPN services.
Important: You Must Set Your Default MFA Method
You can no longer choose your MFA method during login. Instead, the system uses your default method from Microsoft Sign-In settings.
Am I Affected?
All VPNs except the 5 listed below are changing from Duo to Microsoft MFA for 2-factor authentication. If you use a Purdue VPN that's not on this list, you are affected by this change:
webvpn.pfw.edu/consultant
webvpn.pfw.edu/teleops
webvpn.pfw.edu/student
webvpn.pfw.edu/dwban
webvpn.pfw.edu/gopfw
How do I change my Default sign-in method?
1. Go to: https://mysignins.microsoft.com/security-info
2. Sign in with your Purdue career account.
3. Locate Sign-in method when most advisable is unavailable (look for small text next to the Change link).
4. Click Change and set the desired Microsoft MFA default method.
5. Save changes and test by signing into the VPN.
Need Additional Assistance?
If you’re unsure how to update your MFA settings or which method to choose, contact Purdue IT support at 765-494-4000 for assistance setting your default MFA method/other Microsoft MFA issues.
Recommended MFA Method
We strongly recommend setting your default method to:
Microsoft Authentication - Notification
This method works with all VPN systems, including those systems that don’t allow code entry.
Notice for Thinlinc/Radius Application Users
If you use the web application for ThinLinc, all sign-in methods will allow you to authenticate. If you use the native Thinlinc client or other Radius applications at Purdue, you will need to set the default sign-in method to App Based Authentication - Notification. The other sign-in options do not work for these applications at this time.
