2 Main Types Of PDF Password Protection And When To Use Each

PDF is the best format for digital document management and for many businesses it’s the go-to format for their file management.

It’s one of the most common file formats in any business, but some people are still unaware of its encryption functionalities.

Before we teach you all the different ways to password protect or encrypt your PDF documents, it’s worth going over the 2 main ways you can protect your documents and how. Which are as follows.

User-locked PDF

A user lock protection restricts the readers from taking any further actions in attempts to copy, edit, print, or share the document. 

This feature requires a permission password such that users cannot access those functionalities without it as they are disabled. These advanced functions, therefore, make it very easy for the original file owner or sender to protect the document.

Owner-locked PDF

Owner-lock protection is used to set document restrictions in PDF files. Some of the document restrictions that could be placed by the owner include;

  • Printing.
  • Changing the document.
  • Document assembly.
  • Content copying.
  • Content copying for accessibility.
  • Page and graphics extraction.
  • Commenting.
  • Filling of form fields.
  • Signing.
  • Creation of template pages.

Other ways to protect or secure your PDF documents include:

Why Not Use Adobe Acrobat To Password Protect Your PDF Documents

Now, if you’re wondering why you should or shouldn’t use Adobe Acrobat to protect your sensitive documents, here’s what you need to know.

Acrobat (or Adobe Acrobat Reader) is a free PDF file reader tool that was released in 1993 to help view, print, annotate, and edit PDF documents. Since then, more and more features have been added.

However, Adobe is not often recommended as the ideal PDF tool to protect or encrypt your documents. There have been issues in the past regarding some of its security flaws. And if you want advanced features (as well as future updates, quarterly security enhancements, software improvements, etc.), you need to pay for Adobe Acrobat Pro.

Meanwhile, if you’re looking to simply password protect or encrypt your PDF documents, there are easier ways to do so.

How To Unlock A Password Protected PDF File

What if you want to unlock a password-protected PDF instead?

There are ways to get around the protection. 

If you know what the original password is, you can simply remove the lock.

However, if you’re not the owner of the document, there are still certain steps you can take. Read more on that below.

Now, while the exact steps of unlocking a password-protected PDF file might vary depending on the software, usually they are as follows:

  • Open your PDF document.
  • Choose ‘tools’, ‘encrypt’, ‘remove security’.
  • If the PDF document has a Document Open Password, click OK to remove it.
  • If your PDF document has a permissions password, type the correct password in the box and click OK to remove it.

Why remove a password?

Password removal may sound suspicious. But more often than not, passwords need to be removed for convenience's sake.

The most common reason to remove a password from a secured PDF file is that you don't need that information anymore or it's no longer relevant.

If the content of the PDF is no longer sensitive or private, it's time to remove the lock.

And you can unlock a PDF document with just about any tools mentioned above - with or without Adobe Acrobat, online, with Word, and more.

Finally, the last form of password protection we’ll cover has to do with Google Docs.

Google Docs is well known by professionals for its user-friendly features that help users create and make edits to documents online. 

Just as easy it is to use Google Docs for document collaboration, the chances of sensitive information getting out increases with each share.

Fortunately, it’s quite easy to password protect your Google Docs files. 

You can either use a Google Drive password extension or convert your file to a Word or PDF document.
