Why? It seems common that if you can supply the email you signed up with, you can recover your username and get a password reset. Especially true if the website is not somewhere you go to very frequently like the original comment seems to be insinuating and you are using different passwords for every account you make.

Yes, it's being able to use a password reset function. I have different passwords for all sites and with some more strict password rules, I know I'll struggle to remember it.

I do use a password vault, but only for really important accounts.
