Duo Two Factor Authentication

SUNY Plattsburgh has enabled two-factor authentication using DUO.

Two-factor authentication serves as an extra layer of security designed to prevent unauthorized access to your account and personal information.

Duo protects your Plattsburgh account by requiring two forms of authentication to verify your identity when logging into Plattsburgh services:

  • Something you know: your Plattsburgh NetID and password
  • Something you have: a physical device (such as mobile phone, tablet, or landline phone)

Duo was enforced for all Faculty/Staff in Fall of 2019.

Student enrollment begins January 27th 2020.
There will be a 30 day opt-in period where students will be presented with the screen, but not forced to enroll in Duo. You will be given an option to bypass the enrollment screen. After 30 days enrollment will be required.


Step One

Authenticate to any SUNY Plattsburgh application like you normally would.
