I prefer (thus far anyway) to run my forum showing usernames vs. real names, and I’ve made the real name field optional.
But some of my Google OAuth2 (“Sign in with Google”) users have gotten what are apparently default usernames of “User1”, “User2”, etc.
I really don’t like having these generic defaults in the mix.
It looks like this occurs here on meta as well:
I don’t know why this happens for a few Google OAuth2 users but not for most. I’d welcome any insight.
I suppose I could rethink my emphasis on usernames. But is there any way to prevent this “User[X]” behavior, short of disabling Oauth2 signups?
