What is the Purpose of 2-Step Login?
After entering your password into a system (step 1) that is protected by Duo, you will be prompted to approve the login using another device (step 2).
2-Step Login adds an extra layer of security. Even if someone has your password, they will not be able to get into a system that requires Duo. No one can get into the system unless the login is approved with Duo.
Duo will challenge users during the login process if they are registered Duo-user and the service is protected by Duo:
RDP Gateway Connections
Stony Brook's VPN
VPN
SeaWulf
LastPass Enterprise
Single Sign-On
Virtual SINC Site
Save your DUO authentication in your personal device for 7 days so you don't need to DUO authenticate as frequently.
The recommended method is to setup up Duo Mobile on a smart phone to receive push notifications.
A push notification is a message that pops up on your smart phone and allows you to approve the login and finish the authentication process into a protected system, or deny the login if you suspect it is fraudulent.
