We already know that PDF files are easy to read; it doesn´t change the format after opening, and it´s supported by any operating system. Most importantly, one can restrict their PDF file from copying and editing in order to prevent any misuse or mishandling of information by setting a password. A PDF file may be encrypted for security, or digitally signed for authentication. There are mainly two sorts of passwords – one to open the file or document known as the “PDF User Password” and the other password that limits printing and altering, known as the “PDF Owner Password.”
The customary security provided by Acrobat PDF consists of two different methods and two different passwords – the user password, which encrypts the file and prevents opening, and the owner password, which specifies operations that should be restricted even after the document is decrypted, which can include printing, copying text/graphics out of the document, and modifying the document.
If your PDF file is protected with both types of passwords, it can be opened with either password. However, only the Owner password allows the user to change the restricted features. Because of the added security, setting both types of passwords is often beneficial.
Please note: You cannot add passwords to a signed or certified document.
In Adobe Acrobat, the User Password is known as Document Open password which encrypts the file. The owner’s password does not encrypt the file, instead relies on client software to respect these restrictions. An “owner password” can be removed by much commonly available software or application, including some free online services also (which are not at all safe to use). Thus, the use restrictions that a document author places on a PDF document are not secure and cannot be assured once the file is distributed; this warning is displayed when applying such restrictions using Adobe Acrobat software to create or edit PDF files.

In Adobe Acrobat PDF, the owner password is known as Permission Password. A PDF owner password is a password that is used to restrict documents in PDF files. In Adobe Acrobat, the owner password is known as the change permissions password. Sometimes also referred as a restriction password, PDF permissions password, or PDF master password depending on the PDF users.
PDF owner password gives the capability to protect your important files and control who interacts with them. This is what makes PDF the ideal format for business contracts and legal documents. It’s also perfect for securing your electronic diary! But when you need to share your files, sometimes you need to know how to unlock PDF as well.
