One reliable solution I have discovered is LastPass.
LastPass is a free online password manager and Form Filler that makes your web browsing easier and more secure. LastPass supports IE and Firefox as Plugins (Opera, Safari, Chrome, iPhone, Opera Mini via Bookmarklets), allows you to import from every major password storage vendor and export too, captures passwords that other managers won’t including many AJAX forms, and allows you to make strong passwords easily. Your sensitive data is encrypted _locally_ before upload so even LastPass cannot get access to it. One Time Passwords & Screen Keyboard help protect your master password.
