## User Password Breach

> **PLAN:** This feature requires [at least a Starter plan](https://fusionauth.io/docs/concepts/plans-and-limits/plans-features.md#starter-features).

Available since `1.15.0`

This event is generated when Reactor detects a user is using a vulnerable, or breached password. This event will only occur during login when the Tenant is not configured to require the user to change their password. All other breached password detections will occur during password validation and because the user will not be allowed to use the password.

Event type

user.password.breach

### Event Scope

This is a tenant-scoped event.

Prior to version `1.37.0` this event was sent to all webhooks, and it was a webhook's responsibility to filter on the **tenantId** field.

In version `1.37.0` and later, this event will only be sent to tenants for which webhooks for this event are enabled.

### Transaction Compatibility

This event is transactional. The final state of the operation which caused the webhook is not persisted to FusionAuth until after the webhook finishes; [learn more](https://fusionauth.io/docs/events/webhooks/writing-a-webhook.md#calling-fusionauth-apis-in-webhooks)
