Cannot Remove PDF Password with the Document Open Password
Question details
The user is able to open a PDF using a document open password but is restricted from removing the password or modifying the document's security settings.
- Product
- Device & OS
- not provided
- Scenario
- Attempting to permanently remove password protection or change security permissions on a locked PDF file.
- Observed behavior
- The PDF reader requires a separate permissions password to modify security settings, rejecting the document open password as insufficient.
Check the document's security properties (usually under File > Properties > Security) to confirm exactly which restrictions are applied and whether a dedicated permissions password is set.
Enter the Permissions Password to Remove Security
The officially supported method to remove PDF security is by entering the permissions password, which is distinct from the document open password.
PDF files frequently utilize two distinct types of passwords: a Document Open Password (used strictly to view the file) and a Permissions Password (used to restrict editing, printing, and security alterations).
Even if you possess the document open password and can successfully read the file, standard PDF security protocols prevent you from changing the file's security level without the permissions password.
Contact the original author or the person who sent you the document and request the permissions password (also known as the master password).
Open the PDF in your PDF editor, navigate to the Protect or Security tab on the top ribbon, and select 'Remove Security' or 'Encrypt'.
When prompted by the security dialogue box, input the permissions password.
Click 'OK' and save the document (Ctrl + S) to permanently apply the unrestricted state.
Request an Unrestricted Copy from the Owner
If the permissions password is lost or unavailable, requesting a clean, unrestricted copy is the most reliable workaround.
Easily Manage PDF Passwords and Permissions with WPS Office
WPS Office provides a comprehensive suite of PDF tools, allowing you to easily add, manage, or remove both Document Open and Permissions passwords when you have the correct credentials.
- 1. Open the Protected PDF: Launch WPS Office, open your protected PDF file, and enter the Document Open password to view it.
- 2. Navigate to the Protect Tab: Click on the 'Protect' tab in the top menu ribbon, then select 'Encrypt' to access the password settings.
- 3. Remove Passwords: Uncheck the boxes next to 'Set open password' and 'Set password to edit and extract'. You will be prompted to enter the Permissions Password to authorize this change.
- 4. Confirm and Save: Click 'Confirm' and then save the document. Your PDF is now free of all password restrictions.
Frequently Asked Questions
What is the exact difference between a Document Open password and a Permissions password?
A Document Open password is required simply to open and view the PDF. A Permissions password (often called a master password) is used to restrict specific actions like printing, copying text, editing, or changing the file's overarching security settings.
Can I remove the permissions password if I only have the open password?
No. Standard PDF security protocols require the permissions password to alter any security settings. The open password alone allows viewing but does not grant administrative rights over the document.
Is there a way to bypass the permissions password using PDF software?
By design, the permissions password cannot be bypassed using standard PDF readers or editors like WPS Office or Adobe Acrobat. You must obtain the correct password from the file owner to legitimately change the document's restrictions.
