# IP Authorization

The **IP Authorization** feature allows you to restrict login access to selected IP addresses or entire ranges. This ensures that even if your password is compromised, access to your account remains secure.

To configure this option:

1. Log in to the application.
2. Go to **Account** → **Settings** → **Security**.
3. In the **IP Authorization** section, find the field for entering addresses.
4. Enter a specific IP address or provide an IP mask to define the entire access range, then click **Add**. To remove an IP address, click the **Delete** button next to the corresponding entry in the IP list.
