Based on the provided knowledge sources, there is no explicit documentation or example showing a dedicated Ory Kratos webhook that triggers specifically on failed login attempts. However, there is mention of a "failed login webhook" being discussed as a possible solution for implementing account lockout or throttling logic, but it is not currently a built-in feature. The Ory team suggests that such logic could be implemented using webhooks if/when such a feature is available, but as of now, it appears to be a feature request or under discussion, not something that is natively supported in Kratos at this time. The recommended approach for now is to use external systems (like a WAF) or to implement custom logic if you need to handle failed login events specifically within Kratos itself. There is also mention of live event streams that include a LoginFailed event, which could potentially be used for similar purposes, but this is not the same as a webhook directly triggered by a failed login in the self-service flow configuration [Event names](https://www.ory.sh/docs/actions/live-events#event-names) [Throttling repeated login requests & account lock](https://github.com/ory/kratos/issues/3037). If you need to trigger custom logic on failed logins, you may want to look into Ory Actions and live event streams, but a direct webhook for failed logins is not currently documented as available.
