You pretty much answered your own question. Money (all versions with Billpay)
utilizes Checkfree, not MyCheckfree. If you need further clarification,
contact Money support.

It looks like 2007 version offers bill pay using Checkfree service. I do have
an account with mycheckfree.com, but login in Money 2007 demands ssn and four

pin. Please help
