In **Settings > Authentication for mobile apps > Simple Profile Authentication**, you can see which API keys allow Simple Profile Authentication. Simple Profile Authentication is automatically marked as **enabled** if at least one such key exists.

To learn how to enable this type of authentication for an API key and then implement is see ["Simple Profile Authentication" in the Developer Guide](/developers/mobile-sdk/user-identification-and-authorization/simple-authentication).

From the **Authentication for mobile apps view**, you can:
- Click a key to open its details in a new window.
- Click **Manage API keys** to go to API key settings, where you can create or edit keys.
