## What it is
Auth0 Lock is an embeddable, configurable login form widget for web applications that integrates with the Auth0 identity platform. It supports standard email/password login, passwordless flows, and social identity providers via Auth0 connections.

## Use cases
- add a login and signup form to a single-page web app
- let users sign in with social identity providers like Google or Facebook
- implement passwordless login via email or SMS one-time codes
- embed a customizable branded login widget in a web application
- authenticate users against an Auth0 tenant from the browser
- handle authentication callbacks and token retrieval in a SPA

## When to choose
- you already use Auth0 as your identity provider and want a ready-made login UI
- you need a quick, configurable login form with social and passwordless support
- you want an embeddable widget rather than building a custom login page

## When to avoid
- you don't use Auth0 and need authentication against your own user store
- you need full control over the login UI and flows (prefer Auth0 Universal Login or a custom implementation)
- you're building a native mobile app (use Auth0's mobile SDKs instead)
