One of the most common ways to authenticate a user is by validating a username and password.
|
||||
Spring Security provides comprehensive support for authenticating with a username and password.
|
||||
|
||||
You can configure username and password authentication using the following:

The preceding configuration automatically registers an xref:servlet/authentication/passwords/in-memory.adoc[in-memory `UserDetailsService`] with the `SecurityFilterChain`, registers the xref:servlet/authentication/passwords/dao-authentication-provider.adoc[`DaoAuthenticationProvider`] with the default xref:servlet/authentication/architecture.adoc#servlet-authentication-authenticationmanager[`AuthenticationManager`], and enables xref:servlet/authentication/passwords/form.adoc[Form Login] and xref:servlet/authentication/passwords/basic.adoc[HTTP Basic] authentication.

== Publish an `AuthenticationManager` bean
|
||||
|
||||
A fairly common requirement is publishing an `AuthenticationManager` bean to allow for custom authentication, such as in a `@Service` or Spring MVC `@Controller`.
|
||||
For example, you may want to authenticate users via a REST API instead of using xref:servlet/authentication/passwords/form.adoc[Form Login].
|
||||
|
||||
You can publish such an `AuthenticationManager` for custom authentication scenarios using the following configuration:
|
||||
|
||||
.Publish `AuthenticationManager` bean for Custom Authentication

[NOTE]
|
||||
====
|
||||
In this example, it is your responsibility to save the authenticated user in the `SecurityContextRepository` if needed.
|
||||
For example, if using the `HttpSession` to persist the `SecurityContext` between requests, you can use xref:servlet/authentication/persistence.adoc#httpsecuritycontextrepository[`HttpSessionSecurityContextRepository`].

[[customize-global-authentication-manager]]
|
||||
== Customize the `AuthenticationManager`
|
||||
|
||||
Normally, Spring Security builds an `AuthenticationManager` internally composed of a `DaoAuthenticationProvider` for username/password authentication.
|
||||
In certain cases, it may still be desired to customize the instance of `AuthenticationManager` used by Spring Security.
|
||||
For example, you may need to simply disable xref:servlet/authentication/architecture.adoc#servlet-authentication-providermanager-erasing-credentials[credential erasure] for cached users.
|
||||
|
||||
The recommended way to do this is to simply publish your own `AuthenticationManager` bean, and Spring Security will use it.
|
||||
You can publish an `AuthenticationManager` using the following configuration:
|
||||
|
||||
.Publish `AuthenticationManager` bean for Spring Security
