To protect your PDF files to restrict other user, set security password using Acrobat Reader version 9.0.

To set password:

  • Go to File, click Document Security
  • Wait to prompt Document Security window
  • In Security Options, choose Acrobat Standard Security
  • Standard Security window will appear
  • Check the box for "Password Required to Open Document" and "Password Required to Change Permission and Passwords", then enter the User and Master Password
  • Choose the Encryption Level either 40-bit or 128-bit.
  • Check the boxes you want to encrypt
  • Click OK, when you submitted all security settings


Best regards,
