# 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.

For the vast majority of use cases, we recommend Universal Login. It's safe and easy to implement.

You can also use Client-Initiated Backchannel Authentication to authenticate users with a decoupled authentication flow:
