How to remove password for opening pdf? I have the password, but want to remove password with python.

Open the PDF, use doc.authenticate() with the password (must be the owner password), then save to a new file.

It works.
Thanks.

Two more questions.

1. Some files has this "Enable Editing" warning, how to enable with pympdf.
   

2. For some files, when opened, it is "enable scrolling", but for other files, this option is not on, will jump to next page when you scroll.
   How to enable scrolling for alll pdf files as a default option through pymupdf?

This is a mixture of different things: available PDF properties plus features of the viewer you are using (which may or may not correspond to PDF properties).
With PyMuPDF you can only set PDF properties of course. This comprises the following:

1. PDF permissions: an integer consisting of bit flags explained here and to be used in method save. Whether your viewer means PDF_PERM_MODIFY when it says "editing" ... who knows.
2. PDF page mode: what to show when viewing the PDF (TOC Yes/No, embedded files, etc). See here.
3. PDF page layout: things like single or double pages, etc. See here.

You must try out how your viewer translates these PDF terms.
