Why You Should Change PDF File Password?

There are many reasons for changing the password of an already locked PDF file, and we will discuss them in the following points:

1. Protection From Unwanted Editing – The first reason to change PDF password is protection from unwanted editing. If you have shared a PDF document with the password, people may edit the content without your knowledge, creating problems for you in the future. And minor edits may prove catastrophic for critical information like bank statements. Hence, changing the password again will protect your data from any unlawful editing, printing and sharing.
2. Restricting User Access – Another reason to change password on PDF is to limit the access to the document to yourself and the people you trust with the information the PDF file holds. Replacing the PDF password ensures that access to our sensitive data is limited exclusively to trusted individuals, like family members and selected co-workers, as we do not share such critical information with everyone.
3. Password Rotation Policies – Many companies have password-changing protocols to ensure that critical data stays safe inside the company and prevent corporate espionage. As the individual responsible for document security within your company, you must regularly change PDF password, ensuring that no employee gains unofficial access to the passwords for all PDF files.
4. Suspected Password Breach – If you suspect the current PDF password has become compromised due to factors like phishing attacks, social engineering and stolen laptop or mobile, you must quickly change password on PDF file to ensure data security and prevent unlawful access.

These reasons highlight the importance of changing PDF file passwords. We will discuss the solutions to change the password, so keep reading the blog!

We discussed the reasons for changing PDF file passwords in the above section, and now we explore the solutions that will help you secure the data of your PDF files. We will begin with a manual solution to change the password and then proceed to an advanced method.

Manual Solution Using Adobe

The best way to manually change password on PDF file is by using the Adobe Acrobat Pro app and protecting your data from unofficial access. The following points describe the steps to change the PDF file password:

3. Select Change Settings and enter the existing password to begin the PDF password changing process.

4. Check the Require a password to open the document box and type the new password.
