removing app specific password thats not showing

I applied an app specific password to a 3rd party email app. It just asked me to sign on with the password I set so I know it works. However, I want to remove it because its too long to remember but its not showing up under my Sign on at appleid.com. Shows I have no apps assigned. ????? Any suggetions on this fubar?
