How do I delete all existing digital signatures in Adobe Acrobat?

Hi, 

Did we ever figure out how to delete signatures so that we can make useful edits to PDF documents?  

Surely this must be possible in 2021!  

Hello PattiP,

Please follow the path C:\Users\user name\AppData\Roaming\Adobe\Acrobat\DC\Security

This holds the file for all of the signature created Adobe DC.

You be able to delete each signature and they will not appear in the Sign As menu once removed.

I hope this helps. Good Luck

I am having this same problem with Acrobat XI Pro. I created a digital signature but cannot recall the password that I created for it. I guess I didn;t realize how difficult it would be (impossible!) to reset it.

I went so far as to uninstall Acrobat from my computer and reinstall via Creative Cloud but I still cannot reset or delete it.

Has anyone been successful in deleting the digital ID/signature from the new version of Acrobat Pro?

Thank you!

Hi Patti,

You can only delete a digital signature using Acrobat or Reader if you have access to the private key (digital ID) that was used to create the signature. Once upon a time anyone could delete a digital signature in Acrobat (other than a certifying signature), but that was deemed a security flaw and we limited deletion of a signature to only the person that created it in the first place.
