The OAuth 2.0 Client features provide support for the Client role as defined in the https://tools.ietf.org/html/rfc6749#section-1.1[OAuth 2.0 Authorization Framework].
At a high-level, the core features available are:
.Authorization Grant support
* https://tools.ietf.org/html/rfc6749#section-1.3.1[Authorization Code]
* https://tools.ietf.org/html/rfc6749#section-6[Refresh Token]
* https://tools.ietf.org/html/rfc6749#section-1.3.4[Client Credentials]
* https://tools.ietf.org/html/rfc6749#section-1.3.3[Resource Owner Password Credentials]
* https://datatracker.ietf.org/doc/html/rfc7523#section-2.1[JWT Bearer]
.Client Authentication support
* https://datatracker.ietf.org/doc/html/rfc7523#section-2.2[JWT Bearer]
.HTTP Client support
* <<oauth2Client-webclient-webflux, `WebClient` integration for Reactive Environments>> (for requesting protected resources)
The `ServerHttpSecurity.oauth2Client()` DSL provides a number of configuration options for customizing the core components used by OAuth 2.0 Client.
The following code shows the complete configuration options provided by the `ServerHttpSecurity.oauth2Client()` DSL:
.OAuth2 Client Configuration Options

The `ReactiveOAuth2AuthorizedClientManager` is responsible for managing the authorization (or re-authorization) of an OAuth 2.0 Client, in collaboration with one or more `ReactiveOAuth2AuthorizedClientProvider`(s).
The following code shows an example of how to register a `ReactiveOAuth2AuthorizedClientManager` `@Bean` and associate it with a `ReactiveOAuth2AuthorizedClientProvider` composite that provides support for the `authorization_code`, `refresh_token`, `client_credentials` and `password` authorization grant types:
====
.Java
[source,java,role="primary"]
----
@Bean
public ReactiveOAuth2AuthorizedClientManager authorizedClientManager(
ReactiveClientRegistrationRepository clientRegistrationRepository,
ServerOAuth2AuthorizedClientRepository authorizedClientRepository) {
ReactiveOAuth2AuthorizedClientProvider authorizedClientProvider =
ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
.authorizationCode()
.refreshToken()
.clientCredentials()
.password()
.build();
DefaultReactiveOAuth2AuthorizedClientManager authorizedClientManager =
new DefaultReactiveOAuth2AuthorizedClientManager(
clientRegistrationRepository, authorizedClientRepository);
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
return authorizedClientManager;
}
----
.Kotlin
[source,kotlin,role="secondary"]
----
@Bean
fun authorizedClientManager(
clientRegistrationRepository: ReactiveClientRegistrationRepository,
authorizedClientRepository: ServerOAuth2AuthorizedClientRepository): ReactiveOAuth2AuthorizedClientManager {
val authorizedClientProvider: ReactiveOAuth2AuthorizedClientProvider = ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
.authorizationCode()
.refreshToken()
.clientCredentials()
.password()
.build()
val authorizedClientManager = DefaultReactiveOAuth2AuthorizedClientManager(
clientRegistrationRepository, authorizedClientRepository)
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
return authorizedClientManager
}
