Every website you visit wants a registration. User names, passwords, hints, what email you signed up with….. Who can remember it all ?
My personal favorite method for non critical passwords ( ie. not for banking, credit cards and other stuff that really matters ) is to use PassPack.com
I know a few others that have used it and to date we have never experienced any compromised security. It seems pretty secure. Just always make sure you are on https://www.passpack.com and not some other website pretending to be.
Check it out.
