Hi Kyle,
Maybe I did not explain properly.
These are the fields I have on the registration page. First Name, Last Name, Email, Password and Verify Password. I do not have a "Username" field on the page.
After the user registers, they only need their "Email" and "Password" in order to login. However, if they lose their password, the "Lost Your Password" page is asking for a "Username" and "Email" address in order to retrieve it.
I guess I'm trying to figure if the "Username" is ALWAYS required for registration in the event you lose your password?
