How to Password Protect a PDF File without Acrobat

When working on sensitive information and sharing it with specific people, you shouldn’t enable all types of users to open and view it. Imagine your email is hacked and all the credentials or proposal files are stolen, this affects a lot to your business, especially your reputation.

That’s why it’s necessary to lock your PDF files before sending it as an attachment through emails. This helps prevent people from copying and editing your information.

Adobe Acrobat Reader allows you to protect a PDF file with a password. However, this method doesn’t seem to be a great recommendation due to a few system and security issues. Don’t worry, there are multiple other solutions you can apply.

In this article, we will discuss the main reasons why Acrobat shouldn’t be your priority when securing a PDF file with a password. Then, we will look at 2 alternatives to do so with ease.

Why don’t you need Acrobat to password protect a PDF file?

Acrobat, also known as Adobe Acrobat Reader, comes as a free PDF file reader tool released in 1993 used to view, print, sign, and annotate PDFs. On top of that, it enables you to limit access to a PDF via passwords.

However, you can’t password protect your PDF online. It’s possible for you to lock the file and send it via an email attachment. Recipients have to download it then enter the correct password to view the content.

What’s more, Acrobat is not often recommended as an ideal PDF password protection solution due to some security flaws caused by the tool. It may make your computer heavy and slow to run too.

There are different methods you can apply to secure PDFs with a password, either offline or online. Wanna encrypt a PDF file for email and require users to enter passwords when accessing it on the local computer? Use Microsoft Office’s built-in encryption tool. In case you intend to upload PDF files to your WordPress site and lock them there, install a file password protection plugin.

Microsoft Office’s built-in encryption tools

Since Microsoft Office 2010, you are able to password protect a PDF file exported from a Word document. To get started securing your file on the local computer:

  1. Open a Word document via Microsoft Word
  2. Click File and choose Save As
  3. Select Browse where the PDF will be saved
    ppwp-word-document-save-as
  4. Pick PDF (*.pdf) from the Save as type dropdown
  5. Hit the Option button
    ppwp-save-as-pdf copy
  6. Enable the Encrypt the document with a password option then click OK
    ppwp-encrypt-document-with-password copy
  7. Enter and reenter your password and click OK
    ppwp-password-protect-pdf

The file becomes protected now. People have to enter the correct password in order to view it. You can find this method beneficial when you share the computer with others but don’t want them to snoop around your private files.

Instead of locking the PDF file offline, you can add it to your WordPress website then wrap the file with a password form. This helps you save and share your files easily.

WordPress doesn’t come equipped with a default feature to password protect your files. To do so, you need a third-party plugin.

Password Protect WordPress Pro and Prevent Direct Access Gold

While the former plugin enables you to cover a PDF file with a password form, the latter helps with downloading management. In other words, you will have your file protected with 2 security layers: a password form and a private download link. When users fill the correct password in the form, they can access the PDF with its protected URL. They are permitted to use the link and download the file in a period of time or a number of clicks.

The shortcode is explained as follows

  • Passwords – Please enter your password. You should make a strong password that has at least 8 characters, including numbers, letters, and special characters.
  • Cookie – The expiration time after which users have to re-enter passwords.
