Mint.com allows you to keep track of many accounts in one place.
You give them the information related to your accounts and they will organize and aggregate all the information in one place. You can even set it up so that you get an email a week before any bill is due or any bigger transactions have posted to your accounts.
Worried about security? From the NYTimes article about mint.com:
"Intuit’s privacy and security policy, though, suggests the company is serious about protecting your data. Among other things, Intuit encrypts all communications between you and the company, and its internal data-handling policies are intended to minimize the chances that an employee can see your information."
