Frequently Asked Questions

Why can't I find the Trust Manager in my Adobe Acrobat mobile app?

The Trust Manager is a robust security feature designed specifically for the desktop versions of Adobe Acrobat and Adobe Reader. The mobile app features a simplified settings menu and does not include the Trust Manager section.

What settings can I change inside the Adobe Acrobat Trust Manager?

Within the Trust Manager on desktop, you can manage trusted identity certificates, control automatic updates for trusted lists, and set policies for how PDFs interact with multimedia and external web links.

Is it possible to manage PDF trust settings directly from my online Adobe account?

No, your online Adobe account only manages profile information, subscriptions, and account-level security. Document-specific trust settings must be configured directly within the desktop application's Preferences menu.
