You will need access to a mobile device or desktop with a multi-factor authentication (MFA) app installed such as Google Authenticator or Authy. Additionally, you will need access to your work email address.
Click here to access the registration page. Fill out the registration form using an approved email address (e.g. work email) and click "Register". If you're registering with a CAC, setting up a password is optional if you only want to access your account using a CAC.
Setup MFA by scanning the QR code with your MFA app or manually entering the provided code. This will create a 6-digit time-based one-time password (TOTP) that changes every 30 seconds. Enter the 6-digit TOTP and type in a device name (can be anything).
You will receive an email with a link to verify your email address. Click “Link to e-mail address verification” or copy the URL into a web browser (do not use Internet Explorer).
Validate your email address by selecting "Click here to proceed". On the next screen, click
"Back
to Application".
