Step 4
We click Yes and now we do the following:
- First, we activate the “Request a password to open the document†box and enter the desired password.
- Then we activate the “Restrict the edition and printing of the document†box and define parameters such as print resolution and set the changes that users can make to the file (we assign a password again).
- At the bottom we can define aspects such as Adobe compatibility and type of coding to apply to the file.
Once we define these criteria, we click on "Accept" and proceed to save the file to comply with these conditions, so the user who accesses it must enter the password and can only make the changes that we have authorized in this section..
