How to use multiple user provider in symfony 5?

@lottie 

To use multiple user providers in Symfony 5, you can configure them in the security.yaml file of your Symfony project. Here is an example of how you can configure multiple user providers:

1. Define your user providers in the security.yaml file:

 1

10

security:
    providers:
        user_provider_1:
            entity:
                class: AppEntityUser
                property: email
        user_provider_2:
            entity:
                class: AppEntityAdmin
                property: username

In this example, we have defined two user providers: user_provider_1 which uses the User entity for authentication based on the email property, and user_provider_2 which uses the Admin entity for authentication based on the username property.

1. Specify which user provider to use in your firewall configuration:

security:
    firewalls:
        main:
            provider: user_provider_1
            # other firewall configuration here

In this example, we have specified that the user_provider_1 should be used for authentication in the main firewall. You can specify a different user provider for each firewall if needed.

1. Update your authentication configuration to use the appropriate user provider:

security:
    firewalls:
        main:
            provider: user_provider_1
            form_login:
                login_path: app_login
                check_path: app_login
                default_target_path: dashboard
        admin:
            provider: user_provider_2
            http_basic: true
            # other firewall configuration here

In this example, we have configured the main firewall to use user_provider_1 for form login authentication, and the admin firewall to use user_provider_2 for HTTP basic authentication.

By following these steps, you can configure and use multiple user providers in Symfony 5 for different parts of your application.
