# Enrolling

## About

Enrolling is a process to register your biometric fingerprint with the corresping address that is going to represent the address as an eligible participant in the Humanode consensus protocol. The consensus  doesn't allow an address to be in the validators list for blocks production and validation if the address isn't related to a human that has passed biometric verification. 

## How to do it

Your node should be already running and synced with the network. You session keys are already rotated.

{% content-ref url="/pages/0Rt3J5rDJgdzWcJxPvMw" %}
[Node](/docs/node/overview.md)
{% endcontent-ref %}

Make sure that your expected private key that is going to repesent you in the network is imported into keystore.

{% tabs %}
{% tab title="Launcher" %}
Check the [Node Configuration](/docs/launcher/node-configuration.md#inserting-the-mnemonic) section of the launcher configuration
{% endtab %}

{% tab title="CLI" %}
Check the [Running the node](/docs/distribution/running-the-node.md) section of manual installation.
{% endtab %}
{% endtabs %}

{% hint style="danger" %}
Keep the key secure and safety. In case of losing access to the key you won't be able to continue participation in the Humanode consensus protocol.
{% endhint %}

Scan the QR code and open the web app on your phone.

{% tabs %}
{% tab title="Launcher" %}
The QR code should appear on the dashboard.
{% endtab %}

{% tab title="CLI" %}
See the `humanode-peer bioauth authurl --help` and use that command with proper flags. Don't forget to set the `--chain` option properly.
{% endtab %}
{% endtabs %}

As a result, you should be able to see the following web page on your phone.
