If you are one among these people confused about similar questions, what you should do is to remove the pdf password. But before direct you to the ultimate solution, it will be necessary to reveal you a little background information about "open protected PDF".
User password: also known as user password, it protects your PDF file from opening(viewing).

And in this article, we are going to put a special spotlight on User password which works critically to open protected PDF.
Assuming you have a Adobe in hand, also know the open (user) password, then the easiest way to open password protected PDF, of course, would be "Entering the correct PDF password in the pop-up box”with Adobe itself.
