title: Unable to make django-master-password work
body: <p>I would like to enable a master password in my DRF (React.js + Django) website using <a href="https://github.com/ixc/django-master-password" rel="nofollow noreferrer">django-master-password</a>. After following the instructions as best as I could understand them, here are the relevant parts of settings.py:</p>
  <pre><code>INSTALLED_APPS = [
      'django.contrib.admin',
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.sessions',
      'django.contrib.messages',
      'django.contrib.staticfiles',
      'django_extensions',
  
      # 3rd party apps
      'rest_framework',
      'rest_framework.authtoken',
      'dj_rest_auth',
      'django.contrib.sites',
      'allauth',
      'allauth.account',
      'allauth.socialaccount',
      'dj_rest_auth.registration',
      'corsheaders',
      'import_export',
      'django_admin_logs',
      'master_password',
  
      # Local apps
      'users',  # Responsible for all actions pertaining to user model
      'content',
      'payments'
  ]
  
  MIDDLEWARE = [
      'corsheaders.middleware.CorsMiddleware',
      'django.middleware.security.SecurityMiddleware',
      'django.contrib.sessions.middleware.SessionMiddleware',
      'django.middleware.common.CommonMiddleware',
      'django.middleware.csrf.CsrfViewMiddleware',
      'django.contrib.auth.middleware.AuthenticationMiddleware',
      'django.contrib.messages.middleware.MessageMiddleware',
      'django.middleware.clickjacking.XFrameOptionsMiddleware',
  ]
  
  ACCOUNT_AUTHENTICATION_METHOD = 'email'
  
  AUTHENTICATION_BACKENDS = (
      &quot;django.contrib.auth.backends.ModelBackend&quot;,
      &quot;allauth.account.auth_backends.AuthenticationBackend&quot;,
      &quot;master_password.auth.ModelBackend&quot;
  )
  
  MASTER_PASSWORDS = {
      'Abc123': None
  }
  </code></pre>
  <p>However, when I try to log into a user account with <code>Abc123</code> as password, I still get the response <code>{non_field_errors: [&quot;Unable to log in with provided credentials.&quot;]}</code>. What am I missing?</p>
  <p><strong>Update:</strong> I have submitted an <a href="https://github.com/ixc/django-master-password/issues/3" rel="nofollow noreferrer">issue</a>.</p>
