What are the required fields to create user through social media login? I want to integrate Social Media Login (which is not a module name, I am going to integrate the HybridAuth Social Login module) in my website. So that I just want to know the required (by our website Drupal signup) fields in social sign up process.

I guess that username and email are required, but is the password required?
For Social Media Login Password field is not required. Only Username, Email-ID is required. After register with with social media login, Your account is pending for approval by the site administrator. You will receive an email once your account has been approved and you can then login with your Google account.
