Go to File - Properties - Security and select "Password Security" under "Security Method". Select your settings, enter your password, and you're done.

      I have tried both options for password protect and neither is wokring:

      • the 'protect using password' option is greyed out
      • Trying to set it through password properties asks for the existing password in order to set a new password. This is absurd because there is no existing password and therefore I'm trying to set one. 

      I pay for Adobe apps and not being able to do something as simple as this despite paying $21 a month is ridiculous.

        "This is absurd because there is no existing password and therefore I'm trying to set one "

        The document has a password.

        To change the security you need the permission password.

        This method is not working for me. Neither is the previously successful way of password protecting a PDF doc that I've created myself. At the point where I either Save the doc or Exit & Save - the program renames the file using a number & character hash and tells me it cannot be saved to the folder I've placed it in. This behaviour began after a recent Windows 10 update and persists regardless of logout / login to my PC as well as my Adobe Pro account.

        I'm stumped. Also more than mildly annoyed.

          How does you add a password? What version of Adobe Acrobat does you use?


          Adobe Acrobat Pro DC - Continuous Release / Version 2022.001.20117
          Added the password in two ways . . . using the method described in the blog
          post.
          Also - and usually - by using the Protect Icon in the side tray and
          choosing Protect Using Password.
          I've done this (literally) hundreds of times but it is NOT working as it
          did before the most recent Windows Update(s).
          Attempting a 'Repair Installation' from the Help tab after sending this
          message.
          Thank you for your time - appreciate the assistance.
