Unable to password protect PDF

[arathichhetri]

Hi, I go to File > Properties > Security but there is no option there that lets me password protect. Please see screenshot below. Please can you help with how to troubleshoot this?

Does you use Acrobat Reader or Adobe Acrobat?

Hello Colleen!

I hope you're doing well. We apologize for the delayed response and the trouble.

As requested by our community product expert, could you check what appears under File > Properties > Security and share a screenshot? Is this issue occurring with all PDFs or just a specific one? Also, please ensure you are using Adobe Acrobat and logged in with the Adobe ID associated with your subscription.

Ensure you are on the latest version of Acrobat installed on the machine: 25.001.20432 Planned update, Mar 11, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check. For more information, see this: https://adobe.ly/4iwPufG;
