Device & OS
not provided
Scenario
Managing digital identities and trusted certificates by cleaning up obsolete signature profiles.
Observed behavior
The user cannot find the option to delete an outdated saved signature, as it is no longer visible in Acrobat Pro DC version 2021.0001.20135.

Solution 1Recommended

Remove the Digital ID via Acrobat Preferences

Use the Acrobat Preferences menu to locate your digital IDs and manually remove the obsolete signature profiles.

In newer versions of Adobe Acrobat Pro DC, the management of digital IDs and trusted certificates has been consolidated under the Preferences menu. You will need to access the specific Identities section to remove outdated signatures securely.

1
Open the Preferences Menu

Launch Adobe Acrobat. On Windows, click on 'Edit' from the top menu and select 'Preferences'. On macOS, click on 'Acrobat' in the top menu bar and select 'Preferences'.

2
Navigate to Signatures

In the left-hand pane of the Preferences dialog box, scroll down and click on 'Signatures'.

3
Access Identities & Trusted Certificates

Find the section labeled 'Identities & Trusted Certificates' and click the 'More' button next to it.

4
Select the Obsolete Digital ID

In the new window, expand the 'Digital IDs' folder on the left. Locate and click on the outdated digital ID or signature profile you wish to delete.

5
Remove the Profile

Click the 'Remove ID' button located in the top toolbar to permanently delete the saved signature.

Remove the Digital ID via Acrobat Preferences
Why is the Remove ID button grayed out?: If the 'Remove ID' button is disabled, the digital ID might be tied to your Windows Certificate Store, a macOS Keychain, or a physical smart card. In such cases, the ID must be removed directly from the operating system's credential manager or the smart card software.

Frequently Asked Questions

Can I delete a signature that is already applied to a PDF document?

You can only clear a signature from a document if you were the one who applied it and the document hasn't been permanently locked. Right-click the signature block on the document and select 'Clear Signature'. This removes it from the document, but not from your saved digital IDs.

Where does Acrobat store self-signed digital IDs locally?

Adobe Acrobat typically stores self-signed digital IDs as .pfx or .p12 files on your local hard drive. On Windows, they are often located in the user's AppData\Roaming\Adobe\Acrobat folder.

How do I remove a Windows Digital ID from Acrobat?

Acrobat cannot directly delete digital IDs that are stored in the Windows Certificate Store. To remove these, you must open the Windows 'Manage user certificates' tool (certmgr.msc), locate the certificate under the Personal folder, and delete it there.
