Learn how to set a password to limit access to files in Acrobat on mobile.
With an Acrobat subscription, you can set a password to protect PDFs. This restricts unauthorized access and can prevent printing. Setting a password creates a protected copy of the file, saved as <filename>_protected.pdf in Adobe cloud storage. The original file remains unchanged.
