Hi Tim, Thanks for your response and the details.
In that case, what would be the best approach to have additional credentials for the user? Do I need to create another model/table and link it to User? In that case, how will that get included in the User object? Do I need to create a middleware? I am sorry if some queries seem out of the way as I am new to Django. Thanks.
