I have a form with (among other things) a digital signature field. So I double-click on it and get a popup about my digital signature, and everything looks correct, but it's asking for a password. I haven't used digital signatures in months or years, and have no idea which of my billions of passwords is tied to my Adobe digital ID. Is there a way to retrieve or reset this?
Sorry, no.
If it's for a self-signed digital ID and the person who you're returning the signed document to isn't relying on you to sign with the same digital ID, could can always create a new one.
