What is a PDF Password and How to Add a Password to Your PDF Document?

Securing your digital documents is very important, especially when they include sensitive information. If you want to avoid non-authorized people from accessing the files, there are a few options that can help you with that. One of the most popular ways of securing your files is to use password protection. Have you ever wondered how to secure your PDF documents and what a PDF password is? If yes, this short guide will be perfect for you.

We will explain what the different PDF passwords are as well as how to properly secure your document. We encourage you to read it until the end as it will equip you with the knowledge you need to protect your valuable PDF documents.

What Exactly is a PDF Password?

A PDF password is an additional security feature that allows only authorized people to access your document. Secured password enables restricted access to the PDF file and successfully protects information that is stored in the file.

There are two types of PDF passwords such as open password and permission password. The one you choose depends on your specific security needs and the level of access and permissions you want to grant to the person you share the PDF with.

An open password (also known as a user password) is used to restrict access to a PDF document. With this type of password, you are able to view the document. However, it allows you to perform certain actions within the file, such as making edits, printing, or copying text.

On the other hand, there is a permission password (a master password). This type of password grants access to viewing the document, but can constrain making changes as well as copying it and printing it.

Features of a Secured PDF document

If you are wondering "what is a secured PDF document" or want to make your PDF document a secured one, make sure the file is protected with security measures. These measures usually include implementing password protection or encryption. This way only people who are authorized will be able to see the file and perform certain actions within it.

A secured PDF document is a file that is protected with a password that cannot be easily guessed. Moreover, the password itself has to be properly stored so that it doesn't leak to illegitimate individuals.
