**It is recommended that you copy and save this email and the documents at the below links prior to your date of transition so that you have it for reference after your account has been transitioned.**

Part 3 – Once your account is transitioned you must begin using your Authentication certificate. When you launch Enterprise applications, you have to select other certificate and choose your Authentication certificate (16 digits) to get access.  If you are interested in what the 16 digits mean, look at:
