If you've created your account you've completed Step 1 of Registration.
The next step (Step 2) is to Log In by going to: https://verifiny.com/register and to sign the Facility Participation Agreement (FPA). You sign the FPA by checking the box at the bottom of the agreement.
Once you do this, a copy of the signed FPA and shared secret letter will be mailed to you.
