Symfony 4: How to authenticating users?

Question

I'm starting to learn Symfony. I would like to create an API accessible with authentication. I followed the symfony documentation for creating an API skeleton (composer create-project symfony/skeleton my-project) then I followed the security section (https://symfony.com/doc/current/security.html). I arrived to the part 3a "Authentication & Firewalls". I updated the config/packages/security.yaml file then I installed the profiler.

This is my security.yaml file:

security:
    encoders:
        App\Entity\User:
            algorithm: argon2i
            cost: 12

    # https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
    providers:
        # used to reload user from session & other features (e.g. switch_user)
        app_user_provider:
            entity:
                class: App\Entity\User
                property: username
    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        main:
            anonymous: ~

            # activate different ways to authenticate

            # http_basic: true
            # https://symfony.com/doc/current/security.html#a-configuring-how-your-users-will-authenticate

            # form_login: true
            # https://symfony.com/doc/current/security/form_login_setup.html

    # Easy way to control access for large sections of your site
    # Note: Only the *first* access control that matches will be used
    access_control:
        # - { path: ^/admin, roles: ROLE_ADMIN }
        # - { path: ^/profile, roles: ROLE_USER }

When I go to "http://127.0.0.1:8000/" I have the profiler bar but I'm not authenticated as anonymous, I'm not authenticated at all. So did I forget to do/configure something? This is what I see in the profiler bar:

Answer 1

Try adding

access_control:
    - { path: ^/, roles: IS_AUTHENTICATED_ANONYMOUSLY }
