-crear la entidad User que implemente la interfaz UserInterface
-en config/packages/security.yaml

security:
    encoders:
        App\Entity\User:
            algorithm: bcrypt
            cost: 12
   providers:

                target: /
  access_control:
        - { path: ^/login, roles: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/*, roles: ROLE_ADMIN }

en este caso estamos dando acceso al sitio sólo a los usuarios que tengan el rol ROLE_ADMIN
salvo para el caso de login

-en config/routes.yaml

crear la ruta para logout

logout:
    path: /logout

-en config/packages/framework.yaml

habilitar la session

framework:
    secret: '%env(APP_SECRET)%'
    session:
        # The native PHP session handler will be used
        handler_id: ~

-crear el controlador que manejará el login

voy a insertar un usuario inicial,
pero como necesito saber cual es el password codificado, utilizo el siguiente comando:

php bin/console security:encode-password

e ingreso el password que le quiero asignar.

por ejemplo para "admin"

me devuelve el siguiente password "$2y$12$c6FDDMJQl/AfflUe4.U74OPb1SLKUyJ.eGoRDiR8f6eVCNcTJOk4a"

entonces en la migration agrego la siguiente linea de insercion:

insert into user(username,email,password) values("israel bazan","israelbazan76@gmail.com",$2y$12$c6FDDMJQl/AfflUe4.U74OPb1SLKUyJ.eGoRDiR8f6eVCNcTJOk4a);
