Do you need to open that document fast, and you can’t access it because you forgot your pdf password? In this article, you will learn about the different methods to unlock a PDF password.

We all go through the annoyance of having lost or misplaced something we need in our daily lives, from putting money in a back pocket you can’t recall to locking in your keys in the car or the apartment. Just as these situations have solutions, so does the issue of having forgot your pdf password. Only, recovering a password doesn’t require breaking into anything compared to the former examples.

This article is going to address how to recover access to your document by taking you through;

1. Types of password protection

2. Unlocking forgotten passwords

3. Tips for pdf files not opening

Part 1: Types of password protection

As you interact with pdf documents, you need to know that there are two types of pdf password protection.

The first type is referred to as Password to Edit a PDF File. Here, we have documents locked by the user for specific reasons, and a password is required to access, edit, or modify that data.

The other type is Password to Open a PDF File. In this case, we have owner-locked pdf documents that also require the owner to input the password to enable access. This way, no other party can access the document. Password protection is undoubtedly the ultimate way to protect sensitive files.

What is my password? You must be familiar with this question, right? It’s the most obvious question you ask yourself whenever you are trying to edit a document or need to open a file.

Recovering your documents can be a nightmare if you forget your password. You should also be aware that it’s tougher to remove a password needed for opening than the one required for editing.

Today, there is a myriad of tools that can help you get around a PDF password.
