MyAccounts -2 Rated 5 out of 5 stars
I use pwdhash for 4 email accounts, 3 ISPs, 2 credit cards, 1 credit union, 1 bank, the patent and trademark office, and many e-commerce sites for which I don't want to remember individual passwords. Also I've made it my ie homepage so I can copy-paste into popups that don't accept the @@ prefix. I've only found 1 brokerage and 1 employer that are incompatible in password policy.
If you download the pwdhash.com webpage to a usb flash memory, you can edit the default site address from example.com to a website which you want to access when you are away from a computer with the add-on.
This is a perfect solution for the "common password" problem in that it is common for people to reuse the same password for multiple purposes.
If this were available on my iPhone browser, my life would be even better.
