Multi-Factor Authentication

Beginning March 18, 2019, Duo Multi-Factor Authentication will be  required   to use the VU's Pulse VPN service.

Service Description

Multi-Factor Authentication (MFA) provides an additional layer of security for users logging in to a secure environment.

MFA leverages three types of authentication:

  • Something you know (VUnetID & password)
  • Something you have (physical device)
  • Something you are ( e.g. fingerprint, facial recognition)

Vanderbilt University uses Duo Security as its MFA solution. Duo makes authentication easy by allowing individuals to verify their identity via mobile app, text message, or phone call.

You are welcome to enroll in MFA. However, please contact your application owner to find out if your application currently requires it. VUnetID authentication is required to request Multi-Factor Authentication.

Service Charges or Fees

There are currently no service charges or fees for this service.

If you do not have a smart device or do not wish to use your smart device, you may purchase a Universal 2nd Factor Authentication device (U2F) such as a YubiKey or Google Titan from vendors such as Amazon or Yubico.  These devices can then be enrolled and used as your second factor of authentication.
