Password-protect PDFs

Subscribers to Adobe Acrobat Premium or Adobe Acrobat Pro DC can password protect PDFs by setting a document open password.

When you create a password for a PDF, note the following:

  • The app creates a file copy named “<the file name>_protected” and saves that file to the Adobe Cloud Storage. It does not protect or change the original file.

  • Actions which change the file are blocked on mobile devices, including Fill & Sign, commenting, and editing.

  • You can use the restricted features with desktop Acrobat.

  • You can remove the password with desktop Acrobat (you must know the original password).

  • There is no separate password for edit. If a user can open a file, they can edit the file.

  • Currently, Acrobat Reader mobile app does not support printing of password-protected PDFs.

To password protect a file from within an open PDF or from any file list:

  1. Tap overflowicon

  2. Tap protecticon

  1. Enter a password and confirm it. Use only supported characters.

Forgotten Passwords

The password feature is designed to secure your docs against malicious attacks and unwanted viewing. For this reason, there is no way to retrieve a lost password. Note the following:

  • DC mobile product password protection works identically on the desktop.

  • It’s always a good idea to backup your password in a secure manner if you think you could forget it.

  • When you password protect a file, Acrobat Reader creates a new file. The original file is not password protected, and you can always retrieve that file from your device.
