Stop Unauthorized Access with PDF Passwords – What Is a Password Secured PDF

Have you ever wished you could somehow put some restrictions on your private pdf documents? Making PDF files to share essential data with work partners, classmates, and friends is very common nowadays.

If you’re sharing pdfs that contain sensitive information about your projects, you would like to make sure it’s completely protected from public eyes. Thankfully, password-protecting a PDF file is super easy with common PDF applications like Adobe Acrobat.

To help you secure your PDF files, here we will discuss what is a password secured PDF and how to lock a PDF file. You’ll also learn what to do in case you forget the permissions password. Let’s dive right in.

How Does Password Security Work for PDF Files?

Password-protected PDF files are locked with a passcode so that only the owner of the PDF file can control the access. So, a person can open secure PDFs only if they have the correct password to open the PDF file.

Besides, the security will restrict editing, adding annotations, printing, and other changes for those without a password. Now, here you have two options to add password security to your PDF documents including —

Password Protection

When you add password protection to a PDF document, the PDF content remains unchanged, and anyone with the right PDF password can open it. It’s a very basic yet strong type of security.

Users without a permission password can’t make any changes to the file. So, all your data in a password-protected PDF will remain safe.

Encryption

It’s a stronger method to protect a PDF file where the data of your PDF is encrypted or turned into unreadable cipher texts. Encryption tools use an algorithm and an encryption key for this transformation.

If someone wants to open an encrypted pdf, they must have the key, and it can be a passcode or digital certificate. So, even if an unauthorized person cracks the PDF password, they won’t be able to read what’s in that PDF file.

Choose the PDF document you want to protect and open it in Adobe. If you’re using the website, you can use the drop zone instead to drag and drop files.
