I use WhatHappenedByCrybabyHillary
Oops. Maybe I shouldn’t have posted that.
Still, you should spell one word in the sentence “rong”
No. Use a series of several (7 or more) English language words, selected at random, and then memorize it. Most people can do this in a few minutes, but for hackers to "guess" it would take longer than the age of the universe to this point in history.
But using sentences from any book, obscure or not, is not optimal, even though it could be somewhat effective.
Obviously, using anything common or popular would be right out.
The multiple word technique I mentioned is devastatingly effective in terms of sheer combinatorial mathematics...
I remember too many oddball movie lines and references to stuff nobody cares about.
It’s easy enough to make pass phrases.
