Disregard.

I had only deleted two of three password entries in the security and passwords section. After deleting the OAUTH password, it let me enter my password again but it wouldn't accept the new password I created just a week ago, despite it telling me I had changed it 6 days ago. So, I changed my password, AGAIN, and now it's working again.

Not at all a simple or smooth process and I used to build my own PCs so I do know a thing or two about computers.
