# Settings and API Keys

### API Keys

API keys let applications read prompts through the SDK.

#### Creating a Key

Click **Create key** and provide:

| Field       | Notes                                                        |
| ----------- | ------------------------------------------------------------ |
| Name        | A human label, such as `production`, `ci`, or `local-dev`.   |
| Environment | `pv_live_` for live prompts or `pv_test_` for staging reads. |

Copy the key when it is shown. PromptVault does not show the full key again after creation.

#### Listing Keys

Each key row shows:

| Column      | Meaning                                        |
| ----------- | ---------------------------------------------- |
| Name        | Human label.                                   |
| Prefix      | Short visible prefix used to identify the key. |
| Environment | `live` or `test`.                              |
| Created     | Creation time.                                 |
| Last used   | Best-effort usage timestamp.                   |
| Status      | `Active` or `Revoked`.                         |

#### Revoking

Revoking a key prevents future SDK reads with that key. Existing application processes should be restarted or reconfigured with a replacement key.

### Enable Staging

The staging toggle controls whether the editor offers a Staging save target and whether the Versions tab shows staging controls.

| State    | Effect                                                                         |
| -------- | ------------------------------------------------------------------------------ |
| Disabled | Editor offers Draft and Live. `pv_test_` keys fall back to live.               |
| Enabled  | Editor offers Draft, Staging, and Live. `pv_test_` keys read staging when set. |

Toggling staging does not delete existing prompt versions.

### Sign Out

The **Sign out** action ends the current dashboard session.
