## Pre-requisite:

* This component must be used on a Page set to **Authenticated**. Learn more at: [https://docs.limio.com/product/authentication/authentication-provider-per-page](https://docs.limio.com/product/authentication/authentication-provider-per-page "mention")
* This component checks the `userDetails` object, which is a representation of the authenticated user.
  * `userDetails` is populated by your authentication provider via the JWT token.
  * You must configure your authentication system to include `custom:allow_commerce` attribute as a claim in the JWT token and set it to `"false"`. The component will then block the user from accessing the page.
  * Learn more about how to set up JWT tokens and claims in Limio: [https://docs.limio.com/product/authentication/sso-your-authentication](https://docs.limio.com/product/authentication/sso-your-authentication "mention").
