# Authentication

> One key for your server, one for your apps.

| Key | Looks like | Where it lives | Use it for |
| - | - | - | - |
| **Secret key** | `rk_secret_…` | Your server only | Everything: create and read verifications, templates, databases. |
| **Publishable key** | `pk_live_…` | Inside your Android / iOS app | The native SDKs (by request). Identifies your account, can't read results. |

Create both in the dashboard: **Settings → API**.

```bash theme={"dark"}
Authorization: Bearer rk_secret_...
```

> [!WARNING]
>
> A secret key in an app or a browser is a leak. If it happens, revoke it in the dashboard and create a new one.

The capture link you send to a person needs no key. The link is the credential.
