How do I encrypt an Adobe .pdf file?

It is a best practice to encrypt/password protect documents when they contain protected or private information. This will preserve authorized access and make sure only the person(s) authorized can view the information.

  1. Navigate to Tools > Protect.
  2. Select Encrypt, then click Encrypt with Password.
  3. In the Password Security window, Check the box labeled Require a password to open the document.
  4. Enter a password in the field.

    NOTE: If the password is lost or forgotten, the document cannot be recovered.
