When doing a global Search and Replace we often get an "Authentication" dialog box prompting for a password (most often these VIs are third-party VIs to which we don't have passwords), so the search stops until the user clicks "Skip" and perhaps selects "Skip remaining password prompts for this operation."

Similiarly to the option to "Ignore VIs in vi.lib", there should be an option to skip password protected VIs because, most likely, we won't be able to replace anything in them anyway.
