**Important!** You must activate the **PIN code** feature before linking a security key.
{% endhint %}

1. Go to **Settings → Security Key**.
2. If no keys are linked, the status will display **“Not linked”**. The **“Link”** button is active only if the PIN code is enabled.

5. The key list displays: number, name, creation date, last usage, and the **Delete** button.
