Overview:

What is DUO two-factor authentication? DUO is a cloud-based security company providing two-factor authentication services. Two-factor authentication enhances security by adding a second layer of authentication to your login. This method is stronger than a password alone because two factors confirming you are who you say you are: something you know, such as your password, and something you have, like a cell phone or tablet.  This process ensures that even if a hacker obtains your login credentials, the information is useless without access to the your secondary device.
