Two-Factor Authentication

Also known as: 2FA; Duo 2FA; Multifactor authentication; Duo
Available to: Faculty & Staff

Service Summary

Two-factor authentication is an additional layer of protection when accessing Mason’s restricted applications or system remotely. It helps provide a second layer of protection against the sophisticated tactics of cyber criminals. It makes personal information and Mason's information less vulnerable. Any Mason employee who uses the Cisco AnyConnect VPN is required to use 2FA. 

Mason partnered with Duo Security to deliver 2FA when using the Cisco AnyConnect VPN. Mason employees will log into the VPN with their NetID and Patriot Pass password (1st factor) and confirm their identity using a physical device (2nd factor). The physical device may be a smartphone, tablet, mobile phone, or landline phone.

All users of Mason’s enterprise VPN must adhere to:

Faculty and Staff members must also adhere to:
