## Built-In Security

FusionAuth’s built-in safeguards let you enhance security effortlessly. We check for breached passwords at login, while storing passwords as strongly-hashed strings. No additional code, no complex configuration needed.

## Take Action

Be proactive. When FusionAuth detects a compromised password, you can immediately inform your users of the breach and require them to change their passwords to prevent unauthorized access while protecting sensitive data.

## Be Informed

Stay ahead of security threats with real-time notifications. FusionAuth’s breached password detection can trigger a webhook when it finds compromised credentials. This allows you to integrate with your SIEM systems, or other security tools, for immediate action and improved protection.
