# Login Authentication on Auth0

> Learn about the ways to implement login authentication for your users with Auth0 Universal Login or Embedded Login.

Auth0 offers two ways to implement login authentication for your applications:

* **<Tooltip tip="Universal Login: Your application redirects to Universal Login, hosted on Auth0's Authorization Server, to verify a user's identity." cta="View Glossary" href="/docs/glossary?term=Universal+Login">Universal Login</Tooltip>** where users log in to your application through a page hosted by Auth0.

* **Embedded Login** where users log in to your application through a page you host.

When choosing a login method, we recommend Universal Login for the majority of use cases. It’s safe and easy to implement. While embedded login can grant you more control over the UI, the greater risk factor and maintenance requirements outweighs the benefits.
