With the new Twitch social integration, the name field for users has the value of their email. It used to be their Twitch username.
If someone is changing from the old integration to the new one, which they have to since Twitch is shutting down the old API (see this Twitch Social Integration doesn't work for new Applications - #11 by konrad.sopala) they might accidentally leak users private emails to their web front ends.
Every use of auth0User.name will now show the user’s email once they make the switch to the new integration.
I thought this was worth mentioning here.
I guess what I am suggesting is: it really doesn’t make sense for the name field to have the users email. There is a separate field for that.
