Doesn't matter. Apps downloaded with an Apple ID are forever tied to it, and will always require it to update.
That Apple ID is embedded in the app, and cannot be changed. If you don't know the password for it, the only option is to remove the App that is tied to that Apple ID.
Cancel the prompt, find the App and delete it. If its trying to update it will continue to request it until you delete it.
