It's very frustrating when you can't get into the DC system because you changed your password. It's even more frustrating when you are the only authorized user, and you have a deadline looming. Only the SNP CE Admin user group are the authorized users for your contracting entity (CE) and can access the DC system. Remember, neither the ESC or TDA can get the match lists for you.
This is a good time to do a check to see who has access to DC. Are there others that you thought was active, but their TX-UNPS account has been inactivated since they don't use it? Does their FND-101 (Certificate of Authority) need to be updated?
Don't get caught in a bind. Plan for that back-up user before you need it!
