BREWERDAVE1: .. but what would happen if you didn't have an online account set up ??
have you tried to follow the link?
To answer your question, when you first try to follow the link you are not in a logged-in state and the system does not know whether or not the user has an online account. The choice presented is to log in or to create an online account.
Well that's what happened when I tried.
So create account security is what's important. From memory, the customer account number from the bill is required to register an online account.
later edit -
I can see (now) my original point was not clear as technically I was not taken to my online account, only to the sign-on. Apologies
