Adobe Acrobat uses the term "digital ID" for digital certificate.

If you have already set up a Windows Certificate Security Digital ID in Acrobat, this should be removed to prevent anyone from resetting the Preference back to Windows Certificate Security and thus obtaining unauthorized access to your digital ID.

Remove a Digital Certificate

In Acrobat, select Edit > Preferences

In the Preferences dialog box, select Signatures > Identities & Trusted Certificates > More


Select + Digital IDs. Highlight the certificate you want to remove and click Remove ID

You will not receive a warning so you must keep a back up of your certificate if you wish to reinstall it.

You may remove the certificate by using Detach File for certificates created using older versions of Acrobat where you receive the following error
