The user.login.suspicious webhook event requires the Client Risk Configuration to be enabled at the tenant level. Even though Risk Signals are evaluated by default, the webhook event itself won't fire unless this configuration is explicitly turned on.
To enable it:
- Navigate to Tenants → Select your tenant → Edit → Security tab
- Find the Client Risk Configuration section
- Ensure it's enabled for your tenant
Additionally, verify that the user.login.suspicious event is enabled in the tenant's webhook settings:
- Go to Tenants → Select your tenant → Edit → Webhooks tab
- Confirm
user.login.suspicious is checked/enabled
Once both are configured, your webhook should start receiving user.login.suspicious events along with details about which Risk Signals triggered the suspicious login determination.
About Risk Signals and Email Volume
If you're seeing a significant increase in suspicious login emails after upgrading to 1.68.0 or later, this is because FusionAuth introduced comprehensive Risk Signals in version 1.68.0. Previously, only Impossible Travel was tracked. Now additional signals are evaluated including:
- Untrusted Device
- Unrecognized Device
- Recent Password Change
- Recent Identity Change
- Dormant Password
- Suspicious Agent
All Risk Signals are enabled by default without any configuration changes.
Managing Email Volume
You can tune which Risk Signals trigger suspicious login alerts:
- Go to Tenants → Select tenant → Edit → Security tab → Client Risk Configuration
- Disable specific Risk Signals that are generating too many false positives for your use case
Monitoring Without Sending Emails
You can monitor webhook events while tuning your Risk Signals without sending emails to users:
- Go to your tenant/application settings → Identities tab
- Change the Suspicious Login template to "No Template Selected"
- Monitor your webhook endpoint to see which Risk Signals are triggering
- Fine-tune your Risk Signal configuration
- Re-enable the email template once you're satisfied with the detection accuracy
The webhook fires whenever a Risk Signal threshold is met, independent of whether an email template is configured. This allows you to observe and tune the system before alerting end users.
