How to Adjust Privacy Settings for Acrobat Files on Shared Devices
Question details
The user needs to prevent unauthorized users on shared devices from viewing their personal Acrobat PDF files and recent document history.
- Product
- Adobe Acrobat / Acrobat Reader
- Device & OS
- Desktop, Laptop, iPad
- Scenario
- Sharing a physical device (such as a family iPad or shared office computer) with other users and needing to restrict access to sensitive PDF files.
- Observed behavior
- Acrobat PDF files, cloud documents, and recent file histories remain visible and accessible to other users who access the same device.
Ensure you know the administrator credentials for your computer or device, as creating separate user profiles or adjusting system-level privacy controls will require elevated permissions.
Sign Out of Acrobat and Manage Device User Profiles
The most effective way to secure local and cloud files is to sign out of your accounts after use and rely on separate operating system user profiles.
Acrobat syncs your recent files and Document Cloud files across devices when you are logged in. Leaving your account logged in on a shared device exposes your documents to anyone who uses that device.
Open Adobe Acrobat or Reader, click on your profile icon in the top right corner, and select 'Sign Out' to disconnect your Document Cloud access.
On a Windows PC or Mac, go to your system settings and create a distinct user account with a unique password for each person who uses the computer. This completely separates local files and application data.
Since iPads do not support multiple user profiles natively, always ensure you log out of Adobe Acrobat and any connected cloud storage apps (like Google Drive or Dropbox) before allowing someone else to use the iPad.
Add Password Protection to Sensitive PDF Files
Prevent unauthorized viewing by adding a document open password to your most sensitive Acrobat files.
Easily Password Protect PDFs in WPS Office
WPS Office provides a comprehensive, built-in PDF editor that allows you to encrypt your files, restrict editing, and manage document privacy seamlessly across your desktop and mobile devices.

- 3. Access encryption settings: Click on the 'Encrypt' button to open the document security dialog box.
- 4. Set your password: Check the 'Set Open Password' option, type a secure password, and confirm it in the field below.
- 5. Save the document: Click 'Confirm' and save the PDF file. The document is now securely locked and requires a password to view.
Frequently Asked Questions
Does clearing the recent files list in Acrobat improve privacy?
Yes. Clearing the recent files list prevents other users from seeing the names of documents you recently opened. You can clear it by going to Home > Recent, checking the boxes next to the files, and selecting 'Remove from Recent'.
Will setting a password on a PDF prevent it from being printed by other users?
Only if you set a 'Permissions Password' (also known as a master password). When encrypting the file, you can choose to restrict printing, editing, and copying independently of the document open password.
How do I protect my local PDFs on a shared iPad?
Because iPadOS lacks native multi-user support, the best privacy practice is to set an open password on individual PDF files and save them to a secure cloud location rather than the iPad's local storage. Always sign out of your cloud accounts when finished.
Can I hide specific PDF files on my computer instead of password protecting them?
Yes, you can use your operating system's built-in file hiding features. On Windows, right-click the file, select Properties, and check the 'Hidden' attribute. On a Mac, you can press Command + Shift + Period to toggle hidden files, though password protection is much more secure.
