Permission password: If a permission password is enabled, you can open a PDF file without a password. However, a password is required when you change permission settings.

In order to remove the security from a PDF file, it is necessary to possess the permission password. If your document is encrypted with a permission password and you happen to forget it, it becomes impossible to remove the security using any PDF editing tools.


Once you open the PDF, you can forward it to Protect> Remove Password, and type the permission password to remove password security.

By following this method, you will be able to eliminate both the Open password and the Permissions password. However, if you only wish to disable the Permissions password, you may enter the Set Password section and uncheck Permission Password.

Note: Changes will be not applied to the document until you save the file again.
