From your home computer, open a web browser (NYSERDA recommends Google Chrome) and navigate to www.office.com.

Click "Sign in" and enter your NYSERDA email address.

You'll then be redirected to NYSERDA's secure login page.  Enter your NYSERDA username and NYSERDA password.

Then, you'll be directed to enter in your MFA six digit token.  If you need to configure SecureAuth to gain access to that token, you can follow this tip-sheet.

Then, you'll be logged in and can see the Office365 Main Page.
