# Embedded Login

Embedded Login allows your users to log in directly within your application and transmit credentials to the Auth0 server for authentication. This option is best for teams that want complete control over the login UI/UX while still using Auth0 as the identity provider.

Embedded Login and [Universal Login](/docs/authenticate/login/auth0-universal-login) are not mutually exclusive. For example, you can use Universal Login for initial sign-in and use embedded flows for [factor enrollment](/docs/authenticate/login/embedded-login/use-cases/enrollment) or step-up authentication. To compare the two and decide which combination fits your use case, read [Hosted Login vs. Embedded Login](/docs/authenticate/login/universal-vs-embedded-login).

Auth0 supports Embedded Login with <Tooltip tip="Passwordless: Form of authentication that does not rely on a password as the first factor." cta="View Glossary" href="/docs/glossary?term=Passwordless">Passwordless</Tooltip> connections for multiple application types:

* [Embedded Passwordless Login in Native Applications](/docs/authenticate/passwordless/implement-login/embedded-login/native)
* [Embedded Passwordless Login in Regular Web Applications](/docs/authenticate/passwordless/implement-login/embedded-login/webapps)
* [Embedded Passwordless Authentication for Single-Page Apps](/docs/authenticate/passwordless/implement-login/embedded-login/spa)

Auth0 also supports passkey authentication and enrollment on web, iOS, and Android applications through the **Passkey APIs**:
