Spring Security 6 & JWT Authentication · Lesson

AuthenticationManager and Provider Integration

Connect your JWT filter with Spring Security's `AuthenticationManager` and custom authentication providers.

Orchestrating Authentication

Welcome to the core of Spring Security's authentication process! Today, we'll connect our JWT filter with two vital components: the AuthenticationManager and AuthenticationProvider.

These components work together to verify a user's identity and establish their security context.

The Manager's Core Responsibility

The AuthenticationManager is the central interface in Spring Security for handling authentication requests. Think of it as the conductor of an orchestra.

  • It receives an Authentication object (representing a user's credentials).
  • It delegates the actual authentication task to one or more AuthenticationProviders.
  • If successful, it returns a fully authenticated Authentication object.
