Symfony bundle for login throttling using native Symfony login_throttling feature with pre-configured settings.

This bundle replaces deprecated bundles like anyx/login-gate-bundle by using Symfony's native login throttling feature introduced in Symfony 5.2.

Features

• ✅ Native Symfony login_throttling integration
• ✅ Pre-configured settings with sensible defaults
• ✅ Automatic configuration file generation
• ✅ Command to automatically configure security.yaml
• ✅ Multiple firewalls support - Configure independent throttling for each firewall
• ✅ Database storage support - Store login attempts in database for auditing
• ✅ Custom rate limiter support
• ✅ Compatible with Symfony 7.0 and 8.0
• ✅ Easy migration from anyx/login-gate-bundle
• ✅ Same configuration options as the deprecated bundle
• ✅ Complete test suite with 100% coverage requirement
• ✅ Comprehensive documentation
• ✅ Demo project included
• ✅ GitHub Actions CI/CD

Installation

composer require nowo-tech/login-throttle-bundle

Then, register the bundle in your config/bundles.php:

<?php

return [
  // ...
  Nowo\LoginThrottleBundle\NowoLoginThrottleBundle::class => ['all' => true],
];

Note: If you're using Symfony Flex, the bundle will be registered automatically and a default configuration file will be created at config/packages/nowo_login_throttle.yaml.

Configuration

When installed, a default configuration file is automatically created at config/packages/nowo_login_throttle.yaml (if not using Flex, it will be created on first bundle boot).

You can configure the login throttling settings:

Single Firewall Configuration (Simple):

nowo_login_throttle:
  enabled: true
  max_count_attempts: 3
  timeout: 600     # Ban period in seconds (600 = 10 minutes)
  watch_period: 3600  # See docs: affects DB limiter service name / sharing; counting window is `timeout`
  firewall: 'main'   # Firewall name where login_throttling should be applied
  storage: 'cache'   # Storage backend: 'cache' (default) or 'database'
  rate_limiter: null  # Optional: Custom rate limiter service ID
  cache_pool: 'cache.rate_limiter' # Cache pool for rate limiter state (only when storage=cache)
  lock_factory: null  # Optional: Lock factory service ID (only when storage=cache)

Multiple Firewalls Configuration (Advanced):

nowo_login_throttle:
  firewalls:
    main:
      enabled: true
      max_count_attempts: 3
      timeout: 600
      storage: 'cache'
    api:
      enabled: true
      max_count_attempts: 5
      timeout: 300
      storage: 'database'

See Configuration Documentation for more details on multiple firewalls configuration.

Configuration Options

Setup

Important: The bundle does NOT automatically configure security.yaml. You must run the command below or manually configure login_throttling in security.yaml.

After installing and configuring the bundle, you need to configure your security.yaml file with the login_throttling settings.

Automatic Configuration (Recommended)

Run the provided command to automatically configure security.yaml:

php bin/console nowo:login-throttle:configure-security

This command will:

1. Read your nowo_login_throttle.yaml configuration
2. Add or update login_throttling in your security.yaml
3. Configure all firewalls specified in your bundle configuration (single or multiple)
4. Automatically set the correct rate limiter service IDs (especially important for database storage)

Note: If login_throttling is already configured in security.yaml, the command will skip it unless you use the --force option.

Configuration Priority

What Symfony uses: Symfony's security system reads security.yaml directly. The login_throttling configuration in security.yaml is what actually controls throttling behavior.

What happens if configurations differ:

• If security.yaml has login_throttling configured but nowo_login_throttle.yaml has different values, Symfony will use what's in security.yaml.
• The bundle configuration (nowo_login_throttle.yaml) is only used by the command as a template to update security.yaml.
• To sync them, run: php bin/console nowo:login-throttle:configure-security --force

Best Practice: Configure the bundle in nowo_login_throttle.yaml and run the command to keep security.yaml in sync.

Manual Configuration

Alternatively, you can manually add the login_throttling configuration to your config/packages/security.yaml:

security:
  firewalls:
    main:
      login_throttling:
        max_attempts: 3
        interval: '10 minutes'

The interval value is automatically converted from seconds (in your bundle config) to a human-readable format (e.g., 600 seconds = '10 minutes').

Important: When configuring manually, ensure the configuration matches nowo_login_throttle.yaml to avoid confusion. For database storage, you must also ensure the rate limiter service IDs are correct (they are automatically generated by the bundle when processing configuration).

Migration from anyx/login-gate-bundle

This bundle is designed as a drop-in replacement for anyx/login-gate-bundle. The configuration options are compatible:

Quick Migration

1. Remove old bundle:

composer remove anyx/login-gate-bundle

1. Install new bundle:

composer require nowo-tech/login-throttle-bundle

1. Update configuration:

Before (anyx/login-gate-bundle):

# config/packages/login_gate.yaml
login_gate:
  storages: ['orm']
  options:
    max_count_attempts: 3
    timeout: 600
    watch_period: 3600

After (nowo-tech/login-throttle-bundle):

# config/packages/nowo_login_throttle.yaml
nowo_login_throttle:
  enabled: true
  max_count_attempts: 3
  timeout: 600
  watch_period: 3600
  firewall: 'main'

1. Configure security:

php bin/console nowo:login-throttle:configure-security

1. Clear cache:

php bin/console cache:clear

Complete Migration Guide

How It Works

This bundle uses Symfony's native login_throttling feature, which:

1. Tracks failed login attempts per IP address and username combination
2. Blocks further attempts when the maximum number of attempts is reached
3. Automatically resets after the specified interval
4. Uses Symfony's rate limiter component for efficient tracking

The throttling is handled automatically by Symfony's security system - you don't need to add any code to your controllers or authentication logic.

Requirements

• PHP >= 8.2, < 8.6
• Symfony >= 7.0 || >= 8.0
• Symfony Security Bundle
• Symfony Rate Limiter component

Commands

Configure Security

Automatically configures security.yaml with login_throttling settings:

php bin/console nowo:login-throttle:configure-security

Options:

• --force or -f: Force update even if login_throttling is already configured

Test Coverage

The bundle requires 100% code coverage. The CI/CD pipeline validates this requirement automatically.

Code Quality

The bundle uses PHP-CS-Fixer to enforce code style (PSR-12).

# Check code style
composer cs-check

# Fix code style
composer cs-fix

The GitHub Actions CI/CD pipeline automatically:

• Checks code style on pull requests
• Applies code style fixes on push to main/master
• Validates 100% test coverage
• Runs tests on multiple PHP and Symfony versions
