The number refers to the capacity of working memory and has indeed been revised over time. It's a complicated issue, but 4 units of information is now considered a more accurate approximation. But if you're remembering a password, you're dealing with long-term memory, which doesn't have this limitation.

Long-term memory usually accepts most information from short-term memory not direct sensory input, so it is easier to memorize when you break down things in chunks first.
