# Authentication

### How to generate my API Key?

From Setting page > API Key section, click "Generate API Key" and name your key. The key will be automatically generated.

{% hint style="danger" %}
Copy your API key and store it in a secured place. You'll not be able to see it again then, to avoid any security issue.
{% endhint %}
