About PDF Password
There are two kinds of passwords: User Password and Owner Password.
User Password is also named as Open Password. It is used to protect PDF files from opening. If a PDF file is protected with a User Password, people need to enter the right password to open it.
Owner Password is used to protect PDF files from copying, editing and printing. If a PDF file is protected with an Owner Password, people can read it, but cannot change it.
The standard security provided by PDF has two different passwords: user passwords and owner passwords. A PDF document may be protected by a password for opening (user password) and the document may also specify operations that should be restricted even when the document is decrypted: printing; copying text and graphics out of the document; modifying the document; and adding or modifying text notes (using owner password).
