Adobe Acrobat Reader mobile app allows you to protect your PDF file with password. Subscribers to Adobe Acrobat Premium or Adobe Acrobat Pro DC can password protect PDFs by setting a document open password.

 

Note: Only document open password can be setup using mobile app. For permission password, you would be required Acrobat DC desktop application.

 

Things to keep in mind, when creating password for a PDF:

  • The app creates a file copy named “<the file name>_protected” and saves that file to the Document Cloud. 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.

 

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

  1. Tap pic 1.pngfor iOS and pic2.pngfor Android

  2. Tap pic3.png

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

4. Tap Set Password.
