I have a portal I am trying to use facebook authentication on.   I had the site setup for "EMail as Username" but noticed the facebook accounts had the beginning of the email name before the @ sign.   This would work out great if I had everyone using a username, so I switched to username as username instead of email in site settings.  Now the usernames are Facebook-234243587345962 which who is going to remember this and the emails used for username s before now the users will see enter "Username" instead of "Email" like when they registered.

I am just trying to get some consistency using the authentication systems. 

So when Use Email as Username is checked use the email as the username, and when its unchecked use the beginning of the email or a close auto generated username if taken.  I wish the login system would just allow you to use either your email or username if "use unique email" is set in web config.  That way people can use both ways to remember to log in.  But I know that is asking a lot when I am dealing with this issue still.

Am I the only one that notices this or maybe I have a setting off...

The way I see it is the facebook authentication system while site settings is set to "Use email as Username"  would work for ok if the way its setup was switched and then the actual email account address entered when this setting is on.

End result would be a new facebook user would get a username if unchecked and a email for a username if checked, and never see this FACEBOOK-1234958729456 as a username in the database.  Looks like a bot...

Thank you
