# Feedback to user

Once the **PKSA** receives a challenge request from the **HAS**, it should check if it has access to the required private key.

If it has access to the required private key, it should display information about the request to the user and ask for approval or denial, else it should ignore the request.

{% hint style="info" %}
It is strongly suggested to the **APP** and the **PKSA** to display part or all of the `uuid` of the challenge request to the user. This will allow them to match it on both endpoints and be sure they approve the right request.
{% endhint %}
