What Is Password Protection? 2 Types of PDF Locks You Need to Know About

The password-protection feature is available for different purposes depending on the reason for locking the PDF.

Typically, there are 2 main types of file locks: Document open password and Permissions password.

It’s important to know the type of PDF lock you’re looking at first, in order to determine how to unlock it.

What is a document open password?

When a PDF is fully-locked, it does not allow anyone to view the file without its password. In this case, without the password, you cannot open or view the PDF document.

So, if a PDF file has a document open password, you can’t open or edit it if you don’t know the password.

What is a permission password?

When a PDF file is locked to prevent editing, it can be opened and viewed by people without a password. But when the person viewing it tries to edit, modify or make a comment, it will require the input of the password.

So, if a PDF file has a permission password, you can open it but you can’t edit it.

Now, let’s take a look at what are some of your options whether you know or don’t know the PDF password.

How to Unlock Your PDF File If You Know The Password

If you want to unlock your PDF and you know the password, you can go through these simple steps to open the document.

  1. Go to the folder where your locked PDF is
  2. Open the locked document using any PDF viewer
  3. Input the correct password, and you will be granted access to the file.
