Finder Suddenly Not Accepting Password

I was disabling iCloud Desktop & Documents and moving my files back to my local desktop when I ran into a problem. I disabled these features of iCloud by following some suggestions I found on OSXDaily. While there were several methods discussed, one involved creating new (temporary) Document and Desktop files in Finder locally to hold copies of my files while disabling use of iCloud for my Desktop & Documents, and then moving the contents of those temporary folders into my local Desktop and Documents folders in Finder. I wasn't sure where to put them, but them found I could created those new temporary folders in my Macintosh HD folder in Finder, which required my password to set up. This procedure worked fine, my documents are restored locally, but when I went to delete the empty holder files, Finder would not accept my password. Any advice?
