Auth0 API
Overview
Auth0 is a developer-friendly identity platform that handles user sign-up, login, social login, and multi-factor authentication so you do not have to build auth from scratch. Its management API lets you create users, assign roles, and manage applications programmatically. It is the most popular hosted auth solution for developers building web and mobile apps.
Beginner Tip
Start with the free tier at https://auth0.com — it supports up to 7,500 monthly active users. Use the Auth0 Quickstarts for your framework to get a working login flow in minutes before touching the management API.
