Hi Sohanul Islam Shaon,

Adobe Acrobat is required to set document security and not just the free Reader.

Thanks,
Lori

Hi Ber,

If you have Acrobat Pro., you can secure multiple PDFs (with the same password) by using an Action. Here is a pre-built Action from the Actions Exchange that can do this:

I have about 2000 pdf documents and they need to be password protected. How do I do this in batch?

Hi Kristin -

What program are you using? Adobe Reader will let you see the Security settings, but you can’t make any changes.

The only reason you would have a document that doesn’t allow you to add security is if it has been applied by the document author using another method.

I published my document as a PDF.  When I go to document properties, security, there is no drop down and there is no where for me to click to change the setting.  How do I enable the PDF to allow me to change the security settings?

Hi Adeel -

Password protection must be applied in Acrobat itself, not in Adobe Reader.

We have Adobe Reader X installed on the user system and they want to password protect the PDF files before email it to others. Can we protect the PDF files using Adobe Reader X or do we need to have an Adobe suite or writer?

Hi Donna,

I found that _secure only got appended when there was an existing PDF in the folder - rather than replacing the file…it created the duplicate with _secure.

Yes…software should make our lives easier, but sometimes I have my doubts! Thanks for the info.

Hi Joan -

If you don’t want to have the suffix, open the Action and revise it. To do that, open the Actions panel, click Edit Actions, select the action and edit (remove) the step.

Using a batch mode action to remove the step added in another action would work, but you don’t need to work so hard ;)

When I use the Protect PDF action, _secure is added to the end of the generated protected PDF name - how can I either remove these is batch mode or prevent it from being added?

I’m looking to add a Permissions Password with settings to prevent saving out as Word security to a folder of PDFs.

Hi Dick -

By default, Acrobat shows no security. If you select either or both of the options on the Security tab of the Document Properties, repeat the password’s entry, and then save the file, you have Password Security applied, instead of the no security.

The only reason you would have a document that doesn’t allow you to add security is if it has been applied by the document author using another method.

When I attempt to apply a password to a document, the Security Method shows “no security,” and there is no drop-down option. So now what?
