I believe the First Union/Wachovia "OneStop" is powered by Yodlee. You can log in once a day (or more often) and check all your FF balances, hotel, bank accounts (First Union and others) , mortgage, credit cards, utility bills, bill payment services, insurance, Investments (including 410k), loans, Chat (lycos, excite, msn), ISP mail, news, shopping, travel reservations, mobile downloads, calendars...etc,etc,etc.
I have been using it for a couple of years. They have gotten the bugs out of all the services I use HOWEVER, there area lot of them that I do not use. Works great for me.
They also have a bill payment service (separate) that is great. The only companies that I generally use that do not subscribe are my mortgage company, Comcast cable and America West airlines. You can create custom accounts for these companies so a window will open with one click and then you can log in. One other annoying feature is that some of the subscribing companies do not accept the login direct from OneStop. The "click" will get you there but you still have to login.
Just a disclaimer....I DO NOT work for Wachovia....but my partner does!
I am interested in hearing from some of you that have used OneStop and have found something better as long as it is NOT a Bank of America product. Don't even get me started on my horror stories with them.
