Solution 1Recommended

Delete Unused Digital IDs via Acrobat Preferences

The most direct way to clean up your "Sign As" menu is to detach or remove unwanted digital IDs directly from Acrobat's Digital ID settings.

By navigating to the Identities & Trusted Certificates menu, you can view all digital IDs currently registered to your Adobe Acrobat software. Removing them here will stop them from showing up when you attempt to sign a document.

1
Open Preferences

Launch Adobe Acrobat. Go to "Edit" > "Preferences" (on Windows) or "Acrobat" > "Preferences" (on Mac).

2
Navigate to Signatures

In the left-hand Categories pane, scroll down and select "Signatures".

3
Access Digital IDs

Under the "Identities & Trusted Certificates" section, click the "More" button.

4
Select and Remove the ID

Expand the "Digital IDs" tree on the left and click on "Digital ID Files". Highlight the digital ID you want to remove from the list on the right, click "Detach File" or "Remove ID" in the top toolbar, and confirm your choice.

System Certificates: If the "Remove" button is grayed out, the digital ID is likely stored in your operating system's certificate store (Windows Certificate Store or Mac Keychain). You will need to remove it through your OS settings rather than Acrobat.

Frequently Asked Questions

Will deleting a digital ID invalidate PDFs I have already signed?

No, removing a digital ID from Acrobat's settings only removes it from your "Sign As" menu. Documents previously signed with that ID will remain valid and retain their digital signatures.

Why is the "Remove" button grayed out for my Digital ID?

The "Remove" button may be disabled if the digital ID is stored in your operating system's certificate store (like Windows Certificate Store or Mac Keychain). You must remove these certificates through your OS settings, not directly in Acrobat.

Can I recover a deleted digital ID?

Once a digital ID is removed from Acrobat, it cannot be recovered unless you have a backup of the original certificate file (.pfx or .p12) and its associated password.
