Passwords are usually used to protect documents from being opened or edited. There are two types of passwords in PDF Plus: The Document Open Password and Permissions Password.

The Document Open Password is just that – a password required to open a PDF document. However, it can also restrict editing or printing functions.

A Permissions password gives users permission to change the security settings of a PDF document. When you open a document using the Permissions password, you won’t have to enter it again when changing security settings.

PDF Plus supports 128-bit and 128-bit AES (Advanced Encryption Standard) security standards.

Note: There is no way to recover lost passwords. If possible, keep a backup copy of the document that is not password-protected.
