# Fields of an app

| Field | App type | Description |
| --- | --- | --- |
| App Type | All | Static token or OAuth, see [App types](index.md#administration-app-types). |
| Name, Description | All | The module and the OAuth consent screen show the name. The description is only for administrators. |
| Identifier | All | A unique identifier (UUID) that TYPO3 generates. OAuth apps use it as client ID. |
| Secret | All | Use the button Generate secret token next to the field. The secret is random, and TYPO3 keeps only its SHA-256 digest. A dialog shows the token (static token) or client secret (OAuth) one time. |
| Scopes | All | The scopes that the app can use. See [Scopes](../usage/scopes.md#usage-scopes). |
| Logo | All | An optional image for the OAuth consent screen. |
| Impersonate User | Static token | Required. The backend user of the app. All permissions of this user apply, for example table, field, page and file permissions. |
| Redirect URI | OAuth | The URI of the app. The user goes back to it after the authorization. |
| Access | All | You can disable an app, or limit it to a time range with a start and end date. |
