What are auth0's main functionalities?

User Login

This feature allows users to log in using their username and password. The code sample demonstrates how to use the password grant type to authenticate a user.

const auth0 = require('auth0');
const auth0Client = new auth0.AuthenticationClient({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID'
});

auth0Client.oauth.passwordGrant({
  username: '[e-mail]',
  password: 'password'
}, function(err, response) {
  if (err) {
    console.error(err);
  } else {
    console.log(response);
  }
});

User Signup

This feature allows new users to sign up for an account. The code sample demonstrates how to create a new user using the ManagementClient.

const auth0 = require('auth0');
const auth0Client = new auth0.ManagementClient({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET'
});

const data = {
  email: '[e-mail]',
  password: 'password',
  connection: 'Username-Password-Authentication'
};

auth0Client.createUser(data, function(err, user) {
  if (err) {
    console.error(err);
  } else {
    console.log(user);
  }
});

Password Reset

This feature allows users to reset their password. The code sample demonstrates how to request a password reset email.

const auth0 = require('auth0');
const auth0Client = new auth0.AuthenticationClient({
  domain: 'YOUR_DOMAIN',
  clientId: 'YOUR_CLIENT_ID'
});

auth0Client.requestChangePasswordEmail({
  email: '[e-mail]',
  connection: 'Username-Password-Authentication'
}, function(err, response) {
  if (err) {
    console.error(err);
  } else {
    console.log(response);
  }
});

Social Login

This feature allows users to log in using their social media accounts. The code sample demonstrates how to initiate a login with Google using the WebAuth client.

const auth0 = require('auth0');
const auth0Client = new auth0.WebAuth({
  domain: 'YOUR_DOMAIN',
  clientID: 'YOUR_CLIENT_ID'
});

auth0Client.authorize({
  connection: 'google-oauth2'
});

});

client.getConnection(name, callback)

client.getConnection('my-connection', function (err, connection){
