Password Protecting PDF Documents

on Wednesday, December 5, 2012

It is fairly easy to password protect PDF documents, online or offline. 

Go to the File menu, choose Properties, then go to the Securities tab. Choose Password Security.

Check the Require a Password... checkbox and enter a password.

Click OK, then re-enter the password when prompted.  You'll get a warning that security features won't be enabled until you resave the document.  Click OK to acknowledge the warning, and then OK one last time to close the dialogue box.

Then, resave the document to enable password security (preferably under a different document name so you can tell the two apart).

That's it.  If it's a PDF to be posted online, post it as you would normally.  Anyone trying to open the document,whether online or off, will encounter the dialogue box below.  Once they enter the correct password, they'll be able to access the document.
