Access Trust Manager via Adobe Acrobat Desktop Preferences
Use this solution if you are running the full desktop version of Adobe Acrobat or Adobe Reader and need to manage trusted certificates or update settings.
The Trust Manager is a specific menu found exclusively in the desktop versions of Adobe Acrobat and Adobe Reader. It allows you to manage how the application handles secure documents, multimedia, and external links.
Launch Adobe Acrobat on your desktop. Click on 'Edit' in the top menu bar (or 'Acrobat' if you are on a Mac) and select 'Preferences'.
In the Preferences window, scroll down the left-hand category pane and click on 'Trust Manager'.
From this panel, you can update trusted certificates, manage automatic updates, and configure internet access policies for your PDF files.
Once you have made the necessary adjustments, click 'OK' at the bottom of the window to apply your new settings.

Update Adobe Account Settings Online
Use this method if your goal is to manage your Adobe account profile, subscription, or personal security details rather than document-specific trust settings.
Modify Settings in the Adobe Reader Mobile App
Follow these steps if you are using a smartphone or tablet and need to adjust the limited app preferences available on mobile devices.

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.
