Django app that locks out users after too many failed login attempts.

Project description

Django app that locks out users after too many failed login attempts until release time expires.

Tested on Django 1.4.5.


  • Django


  1. Install python library using pip: pip install django-cerberus
  2. Add cerberus to INSTALLED_APPS in your Django settings file
  3. Sync your database


Add cerberus.decorators.watch_logins decorator to your login view. Example:

class LoginView(FormView):
    template_name = 'example/login.html'
    form_class = AuthenticationForm

    def dispatch(self, request, *args, **kwargs):
        if request.user.is_authenticated():
            return redirect(settings.LOGIN_REDIRECT_URL)
        return super(LoginView, self).dispatch(request, *args, **kwargs)

    def form_valid(self, form):
        user = form.get_user()
        login(self.request, user)
        return super(LoginView, self).form_valid(form)

    def get_success_url(self):
        return reverse('logged_in')


Number of max failed login attempt. Default: 5.
Number of seconds after the failed login attempts are forgotten in seconds. Default: 600.


Each lockout model instance contains username, number of failed login attempts, IP address, user agent details, GET and POST parameters, information if lockout is locked (user tried to log in with wrong credentials at least CERBERUS_MAX_ATTEMPTS times) and if lockout is expired (based on CERBERUS_LOCKOUT_TIME).


You can override cerberus/lockout.html template if you wish. There is lockout instance and lockout_time variable (CERBERUS_LOCKOUT_TIME) available in template context.


Library is by Erik Telepovsky from Pragmatic Mates. See our other libraries.
