Password to Install Updates/Apps Not working - MacBook Pro

do you have your Apple-ID account logged in?

MacOS is not copy-protected in the usual sense:

Apple software downloaded from the Mac App Store, including MacOS, is not copy protected. However, it IS tagged with the Apple-ID of the purchaser when "purchased" (or equivalent. Think of MacOS as purchased on sale for $0.) A valid Apple-ID is required for almost all downloads from the Mac App Store.

You cannot update, upgrade, or install new software based on already-installed software UNLESS your Mac supplies the Apple-ID of the original software.

I have re-set my password multiple times, however that password does not work when I am attempting to install new programs/apps.

What am I supposed to do?

New programs /apps from where exactly?

name a few examples of these apps?

It is either your admin computer password or your appleID/Account password...
