Hi, 

I am adding a new field through field tagger, nintex is an integration in Salesforce in this case however when I added the field and tested no document generation occurred so I selected the nintex doc admin and disconnected it as it seems the authorization expired, (this happened to other of our customers and worked perfectly) then I looked for the nintex admin user and realized the user is no longer part of the project. No one knows the password so we cannot authenticate either authorize.

Is there a way to change the nintex admin for the org? If so how can we achieve this if no one is aware of the password.

Thanks,
