# Adding Security to Your PDF Document

A PDF file can have a user password and a master password. To change a security setting in a file, you need to open it with the Master password.

Opening the PDF file using a User password:

1. Select File > Export to PDF.

The Export to PDF dialog box opens.

3. Specify any password protection you want:

- In the Master Password field, enter the password users must enter before they can open the file. Re-enter the password to confirm it.
- In the User Password field, enter the password users must enter before they can set or change any security options. Re-enter the password to confirm it.

NOTE

Your password must be at least 6 characters long.
