"Capitalization doesn't help very much" can be confusing

"Capitalization doesn't help very much" can be confusing in situations where we're also asking users to use a capital letter.

Would it be possible to use something more along the lines of "Capitalizing the first letter in your password doesn't help very much"?

Edit: I realize that technically speaking "Capitalization" by definition means just that, but I think it could be less ambiguous colloquially speaking.
