Cons

May require careful tuning to avoid locking out legitimate users.

Use Cases

Web Applications: Enhance security by preventing brute force attacks on login forms.
Admin Panels: Protect sensitive admin interfaces from unauthorized access attempts.
SaaS Platforms: Secure user accounts and maintain integrity of the authentication process.

Best Practices

Tune Settings: Adjust failure limits and cooldown periods based on your application's needs.
Monitor Logs: Regularly review logs to identify and address potential security threats.
Combine with Other Security Measures: Use Django-Axes alongside other security practices like rate limiting and strong password policies.

Customization

Custom Lockout Template

Create a custom lockout template to provide a user-friendly message during lockout.

`Your account has been temporarily locked due to too many failed login attempts.`

Custom Handlers

Define custom handlers to perform specific actions during lockout events.

from axes.signals import user_locked_out

def custom_lockout_handler(sender, request, credentials, **kwargs): # Custom logic here pass

user_locked_out.connect(custom_lockout_handler)

Integration

REST Framework Integration

Use with Django REST Framework to protect API endpoints.

from rest_framework.views import APIView from axes.decorators import axes_dispatch

class MyView(APIView): @axes_dispatch def post(self, request): pass

Third-Party Libraries

Integrate with libraries like django-guardian for fine-grained permissions.

Performance Considerations

Database Indexes: Ensure proper indexing on fields used for tracking login attempts.
Cache Management: Use caching strategies to optimize performance when tracking attempts.
Load Testing: Perform load testing to ensure the system can handle peak loads without degrading performance.
