I want to use a different column for provider instead of defalut "email"

[prakash-alpine]

I am running into a problem using "email" as a provider in my User table. I am using the
symmetric_encryption gem to encrypt the email column in my postgres database. This requires to change the name of "email" column to "encrypted_email". Also I am using "username" and "password" as login credentials with Devise instead of "email / password".

With standard Devise gem everything works fine and I am able to login using regular HTML version of login page. However, I can not get the authentication to work with devise_token_auth, since it insists of
using "email" as provider.

My question is: Is there any way I can use a different column (e.g. username) as a provider instead of
default "email" ? I browsed through the code, and it seems that "email" is hard-coded as a provider in session_controller.rb->create() method.

Please help !!!

This is similar and related to: #563 (comment)

My comment there has some information that might be able to help you get the sign in working, but it would be a hacky solution. I suspect it would require your email field be named exactly email, and the uid set in the headers in responses would be the value of that field.
