Does anyone know why My Bing stopped working. I signed out of it, which I never had to do before and now it wants me to sign back in but neither of my email addresses work.

Sorry,  Google put an icon for Bing in their front page and it is no longer on my taskbar.  I signed out (which I never have had to do before) and now Bing doesn't accept either of my email addresses to get back in.  Plus I never had a password to Bing that I know of.  At this point they need to recognize my user name and they tell me that someone else has my hotmail email address and I can't use it.  Can anyone help me out of this fix? I need to somehow delete the icon in google and place one on my taskbar in Windows 10.
