Interface	Description
AuthenticationDetailsSource<C,T>	Provides a `Authentication.getDetails()` object for a given web request.
AuthenticationEventPublisher
AuthenticationManager	Processes an `Authentication` request.
AuthenticationManagerResolver<C>	An interface for resolving an `AuthenticationManager` based on the provided context
AuthenticationProvider	Indicates a class can process a specific `Authentication` implementation.
AuthenticationTrustResolver	Evaluates `Authentication` tokens
ReactiveAuthenticationManager	Determines if the provided `Authentication` can be authenticated.
ReactiveAuthenticationManagerResolver<C>	An interface for resolving a `ReactiveAuthenticationManager` based on the provided context

Class Summary
Class	Description
AbstractAuthenticationToken	Base class for `Authentication` objects.
AbstractUserDetailsReactiveAuthenticationManager	A base `ReactiveAuthenticationManager` that allows subclasses to override and work with `UserDetails` objects.
AccountStatusUserDetailsChecker
AnonymousAuthenticationProvider	An `AuthenticationProvider` implementation that validates `AnonymousAuthenticationToken`s.
AnonymousAuthenticationToken	Represents an anonymous `Authentication`.
AuthenticationTrustResolverImpl	Basic implementation of `AuthenticationTrustResolver`.
CachingUserDetailsService
DefaultAuthenticationEventPublisher	The default strategy for publishing authentication events.
DelegatingReactiveAuthenticationManager	A `ReactiveAuthenticationManager` that delegates to other `ReactiveAuthenticationManager` instances using the result from the first non empty result.
ProviderManager	Iterates an `Authentication` request through a list of `AuthenticationProvider`s.
ReactiveAuthenticationManagerAdapter	Adapts an AuthenticationManager to the reactive APIs.
RememberMeAuthenticationProvider	An `AuthenticationProvider` implementation that validates `RememberMeAuthenticationToken`s.
RememberMeAuthenticationToken	Represents a remembered `Authentication`.
TestingAuthenticationProvider	An `AuthenticationProvider` implementation for the `TestingAuthenticationToken`.
TestingAuthenticationToken	An `Authentication` implementation that is designed for use whilst unit testing.
UserDetailsRepositoryReactiveAuthenticationManager	A `ReactiveAuthenticationManager` that uses a `ReactiveUserDetailsService` to validate the provided username and password.
UsernamePasswordAuthenticationToken	An `Authentication` implementation that is designed for simple presentation of a username and password.

Exception Summary
Exception	Description
AccountExpiredException	Thrown if an authentication request is rejected because the account has expired.
AccountStatusException	Base class for authentication exceptions which are caused by a particular user account status (locked, disabled etc).
AuthenticationCredentialsNotFoundException	Thrown if an authentication request is rejected because there is no `Authentication` object in the `SecurityContext`.
AuthenticationServiceException	Thrown if an authentication request could not be processed due to a system problem.
BadCredentialsException	Thrown if an authentication request is rejected because the credentials are invalid.
CredentialsExpiredException	Thrown if an authentication request is rejected because the account's credentials have expired.
DisabledException	Thrown if an authentication request is rejected because the account is disabled.
InsufficientAuthenticationException	Thrown if an authentication request is rejected because the credentials are not sufficiently trusted.
InternalAuthenticationServiceException	Thrown if an authentication request could not be processed due to a system problem that occurred internally.
LockedException	Thrown if an authentication request is rejected because the account is locked.
ProviderNotFoundException	Thrown by `ProviderManager` if no `AuthenticationProvider` could be found that supports the presented `Authentication` object.

Package org.springframework.security.authentication Description

Core classes and interfaces related to user authentication, which are used throughout Spring Security.

Of key importance is the AuthenticationManager and its default implementation ProviderManager, which maintains a list AuthenticationProviders to which it delegates authentication requests.
