Hi, would anyone know what happens when I discontinue Facebook login? I have been using it for some time now and some of my users have access created that way. What happens if I discontinue the FB login/registration? I assume they won't be able to access their account. Is there any elegant way how to avoid any issues (and discomfort to users) during such transition?

They would need to use the "Forgot Password" tool to reset their local password afterwards.
