Open Password & Permission Password? Learn How to Open Locked PDF

PDFs are great for storing and sharing documents, but they can be difficult to open if locked with a strong password. If you are also stuck in such a situation and wondering how to open a locked PDF, then we are here to assist. Our experts have compiled a step-by-step guide to unlock PDFs using offline and online tools.

Locking a PDF is always considered to protect its content from prying eyes, but what if you want to make changes in the same or forget the password? In such cases, you must need a reliable tool that helps you unlock the PDFs without putting your content privacy at stake.

Here’s a comprehensive guide covering a step-by-step process to open a locked PDF file without affecting its original content quality and formatting. In addition, the guide outlines brief information about open and permission passwords to offer a better idea to the readers. Read on, and let’s take a closer look.

Part 1: What Are the Open Password and Permission Password of a Locked PDF?

PDFs are secured mainly by using two types of passwords: Open Password and Permission Password. While an Open Password is mandatory to lock a PDF, a Permission Password is optional and depends on the user’s preference. Scroll down the page and find a quick overview of both password types.

1. Open Password

Also known as a User Password, an Open Password is a security code required to open a PDF file. It is used to restrict the opening of a PDF. While this password is called the Document Open Password in Adobe Acrobat, other PDF Programs might refer to it as the PDF user password or the PDF Document Open Password.

Remember that Document Open Passwords aren’t hacked easily, but some tools available on the market can do it via a brute-force attack if given enough time. Hence, it is always suggested to set a strong password by combining letters, special characters, and numbers.

2. Permission Password

Next comes a Permission Password, which is sometimes referred to as the master password or owner password. As the name suggests, this password is required to change permission settings. While adding a Permission Password is totally optional, it is always suggested to use it to add an extra layer of security.

With this password, you can set specific document restrictions in the PDF file. If document restrictions are put in place in the latest version of the PDF, it includes the following:

• Printing
• Signing
• Filling forms
• Page and graphics extraction
• Content copying
• Commenting
• Document assembly
• Changing the document
• Content copying for accessibility

Also, depending on your preference, you can allow certain restrictions while blocking others. For example, you could enable commenting while disabling content copying. It simply means that your team members with whom you’ve shared the file can only view the PDF using the Open Password, but they cannot make any changes to the same until and unless they know the owner or permission password. Like Open Password, users should select a robust security code to avoid any type of hacking or compromise.

All in all, PDFs must be secured using both types of passwords to avoid any unauthorized access. However, it should be noted that if the file contains both an open and permission password, it can be opened with either passcode. But, users can change permissions only by using a permission password.
