OAuth2: authenticate with email instead of username

Question

I'm using OAuth2 with django-oauth-toolkit django-rest-framework.

I usually authenticate my users the following way, in order to get a token:

curl -X POST -d "grant_type=password&username=new_user&password=new_user" -u "GZwzDjPM89BceT8a6ypKGMbXnE4jWSzsyqbM3dlK:" http://localhost:8000/o/token/

Is there a way to use the email instead of the username to authenticate my users?

Thanks!

Answer 1

Yes! it is possible by setting the email as username in User model.

class User(AbstractBaseUser, PermissionsMixin):
 email =  models.EmailField(
    verbose_name='email address',
    max_length=255,
    unique=True,
 )
 first_name = models.CharField(max_length=30)
 last_name = models.CharField(max_length=30)

 USERNAME_FIELD = 'email'

then email can now be used as username in the request.

curl -X POST -d "grant_type=password&[email protected]&password=new_user" -u "GZwzDjPM89BceT8a6ypKGMbXnE4jWSzsyqbM3dlK:" http://localhost:8000/o/token/
