My profile shows a linked work email??? Why?

@kupchurch - If you signed up from the zoom.us website initially, it would have created the work email sign on.  The only way to avoid this is if you are part of a company that automatically creates accounts using a Single Sign-On application.  You definitely don't have to sign in using the email method if you don't want to, but it doesn't hurt anything to have it there, and provides a back-up sign-in method if your other methods fail.
