Hi all,
I have implemented Pow for authentication. I am able to successfully register and create session using email and password.

However, I have the following scenario.

  1. I need to implement Pow auth in such a way that users can login/register with email or mobile. With any one of them as mandatory.
    How do I set a schema in such a way that just any one of them is mandatory?
    Also, how do I ensure I will be able to login with either email or mobile? Pow does not allow me to login with mobile number.

  2. I have multiple tables for different roles and each table captures the user profiles belonging to that role. When user logs in based on users table, I need to retrieve the profile info specific to that user from the corresponding table based on user’s role.

Whats the best way to define a mapping between users table and multiple tables that contain the user profile info specific to each role?

Thanks,
Rajasekhar.

You need to edit your migration, to allow for email to be null, and then I would use a check constraint, email is not null or phone_number is not null.

Pow does not allow me to login with mobile number.

You can implement your own authentication function in a custom context to change that, I would take a look here pow/lib/pow/ecto/context.ex at main · pow-auth/pow · GitHub

A combination of a custom authentication and get_by function would probably be enough for your case.
