Pueden probar renombrando el login por signin en caso de que les dé error, así me sirvió.

Buenas tardes, me da el siguiente error al pulsar en el botón Login

Forbidden (403)
CSRF verification failed. Request aborted.

Reason given for failure:

CSRF token missing.

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure:

Your browser is accepting cookies.
The view function passes a request to the template’s render method.
In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.
If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.
The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.
You’re seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.

You can customize this page using the CSRF_FAILURE_VIEW setting.

Agregué la línea de token CSFR pero el problema sigue, gracias!

Hola si al momento de crear el url path('usuarios/login', views.login, name='login'), y cargar la pagina les sale esto "page not found" lo que me funciono a mi fue hacer esto path('usuarios/login/', views.login, name='login')
