How do I get rid of iCloud?

"With the document open, do one of the following:

"Change a password: Choose File > Change Password (from the

File menu at the top of your screen). Enter the requested information,

then click Change Password."

But, I can't open this document, I get this.

So help me, if this ever happens again, I'm going to get rid of my computer and never use one again. Every day I'm looking for my work etc., either searching or sorting through, re-foldering them, for hours per, and in some apps getting hit with a new password demand. Arrrrgh!

But, thanks for your help!!!

Thanks tygb. It looks like iCloud has disappeared and I'm safe!!! But, among the many things that happened with this disaster of about 3 weeks ago, years of my work disappeared. Now, some Pages' documents are still demanding a password where one never existed...and others are not, but opening automatically. How can I get back what I can' t afford to lose?

Really appreciate your help.

Thanks, I've been doing this, a daily grind. But: 'Comments,' my daily document of 700+ pages, 2 are there, named with dates, 1)Sept 4 - 7 Feb 2019, and 2)2019, both demanding a password. And, even so, there are none of the years in between. Yet, I've opened two new Pages' docs and using them daily, no password, but had to reset my defaults, and still doing that, as so much has been interfered with I have start again.

What do you mean by 'enabled"

So I deselected the list in iCloud and now there's nothing on my desktop.

"Apps that store documents and data in iCloud will appear here?" The 6 items are all checked including desktop and documents still nothing on my desktop.
