hi all. i know we can use username instead of email by simply adding username=True to auth, but i wanted to know if there happened to be a way to use either.
for example, i have parent and children users, and i want kids to use username, since they might not have email addresses. but i want parents to use username or email, whichever they can remember. so i'd like a field that accepts EITHER username or email, and checks to see if either would allow login. i will figure out how to do this on my own, but i wanted to see if there were something secret in auth to do it automatically. thanks, matt
