TTUnet VPN upgrade to support security keys for MFA – 5/15/2024 7:30 AM–7:45 AM
On May 15, 2024, at 7:30 AM CDT, the Enterprise IT Security team will upgrade the TTUnet VPN service to add support for FIDO2 security keys with multifactor authentication (MFA). It's anticipated that this change will only take 15 minutes. This upgrade will provide another option for customers to authenticate when signing in to the VPN service. 

As a part of this change, the VPN sign-in process in the GlobalProtect app will now open in your operating system’s default browser instead of a mini-browser built into the GlobalProtect app. On some computers or mobile devices, this may mean that you need to manually switch apps to see the sign-in screen in your browser, such as Chrome, Edge, or Safari.
