# Welcome to Keverd Docs

Keverd helps you identify devices and decide risk on login, checkout, and other sensitive actions.

## How it works

1. **Collect in the browser** with a **public** API key (`kv_pk_…`)
2. Send the returned **`event_id`** to your backend
3. **Verify on the server** with a **secret** API key (`kv_sk_…`)
4. Enforce the returned **`action`**: `allow`, `soft_challenge`, `hard_challenge`, or `block`

* [Webhooks](/server/webhooks)
