Password protection is an important line of defense for any document that contains sensitive information. The ability to create and modify passwords is an absolute necessity if you work in an environment where personal information is regularly handled. Protecting your PDF files by adding a password is a convenient way to make sure others don't open your files without your permission.  Acrobat Professional gives you the fine-grained control you need to manage your documents efficiently and securely. It lets you set permissions for your content and even restrict viewing of that content

 PDF protects are a great way to control access to a document and prevent unauthorized changes. You can also use them to protect documents from being changed. Users can add, delete, rotate, and change all page types, keep and manage their forms and signatures, and lock or unlock form and signature fields. You can also block comments on your blog posts, which can be helpful for getting more readers and engagement. For documents that will live in the cloud, you can encrypt the entire document so that no one will ever find it. This way you make sure that any sensitive information remains completely private. Adobe Acrobat Pro is the premier tool for editing, securing, and sharing PDF documents. Most organizations need a document management solution. So, find resources, tools, and tricks that will help you get the most out of your PDFs.
