The QuickBooks Administrator may access the QuickBooks Service Center from
within QuickBooks to change or modify the login information:
Go to the Company menu and click Advanced Service Administration.
If you have not yet registered for QuickBooks Business Services, or if this
is a new installation of QuickBooks, you will first need to enter your e-mail
address in the Service Login window. Click Next.
Enter your current Login Name and Password. If you are a new user you will
also need to enter some additional information, such as a challenge question
in the event you need access to your password. Click Log In.
Note: If you have the Service Connection preference set to automatically
log in, you will be connected to the Service Center without a login prompt.
If you have more than one company file registered for services, you may
be asked to select a company name from the Select a QuickBooks company drop-down
list. If you are adding this company file to your account, there is an option
for New company in the list. Click Next.
You are now logged into the QuickBooks Service Center. Use the various links
in this window to update your login information, change your password, add
or remove users from your account, or to access QuickBooks Web support options.
