Protect a PDF With Password-Based Access
Add password protection to a PDF before sharing documents that should not be opened freely. The protected copy can require recipients to enter the user password before they can view its contents.
Use Separate Passwords for Viewing and Control
The user password controls access to the document, while the owner password provides full control over its permission settings. Keeping these passwords separate allows recipients to visit the PDF without giving them the credentials used to manage its restrictions.
Select What Recipients Are Allowed to Do
Configure permissions for actions including printing, copying content, modifying pages, adding annotations, filling forms, using accessibility features, and assembling pages. Select the permissions according to how the document is expected to be reviewed or completed.
Common Questions
What is the difference between the user password and the owner password?
The user password is intended for people who need to visit the PDF under the selected permissions. The owner password provides full access and is used to manage or override those restrictions. Share the user password with recipients and keep the owner password private.
Do PDF permissions work in every reader?
Standard PDF readers are expected to follow the permissions stored in the document, but enforcement can vary between applications. Password protection works well for normal access control, but permission settings should not be treated as an absolute way to prevent an authorized viewer from reproducing visible information.
What happens if I forget the owner password?
You may be unable to change or remove the permission settings through standard PDF software without the owner password. Store it in a secure password manager and retain an unprotected original in a controlled location when future editing may be required.
