Yeah I used to be skeptical as well

In a perfect world, that is, if no service stored passwords with risible security, just remembering 2 or 3 strong passwords would be workable

Instead, since we live in a word where several system developers are inexperienced or just plain idiots, there is a need for passwords to be disposable

Password manager are worthy because they allow you to keep several different passwords and the strong password they require hopefully is not stored as MD5 anywhere.
