I’ve been using the Lock library in my web app where both in sign ups and registrations, I have not been requiring username. User simply enters his/her email and password to sign up or login. This has been working fine.
Now, I’m trying to use the login/sign up APIs because in my new React Native app, I needed custom UI. When I test login by calling the API using Postman, I’m getting an error that reads, username is required.
What is the username for the existing users in my database which has been using the “Username-Password-Authentication” i.e. the standard database? I don’t see a username field anywhere when I pulled up a user’s profile through the Auth0 dashboard.
