# How to use withdrawal whitelists

To enhance the security of your crypto withdrawals in the B2CORE UI, it's strongly recommended that you enable the **Withdraw whitelist** option. Once enabled, withdrawals can only be made to addresses added to your whitelist.

To add an address to your withdrawal whitelist:

{% stepper %}
{% step %}
In the B2CORE UI, navigate to **Profile** > **Security**.

{% hint style="info" %}
The names of menu items and other UI elements depend on your broker’s configuration and may differ from those shown in this guide.
{% endhint %}
{% endstep %}

{% step %}
Click **Add** in the **Withdraw whitelist** section on the **Security** page.

{% endstep %}

{% step %}
In the displayed popup, fill in the following fields:

* Select the currency.
* Enter your withdrawal address.
* If required, provide the destination tag or enable the **No destination tag** checkbox.
  {% endstep %}

{% step %}
Click **Submit** to add the address to the whitelist.
{% endstep %}

{% step %}
Enter a verification code sent to your email to confirm the action.
{% endstep %}
{% endstepper %}

You can add multiple addresses to your whitelist if needed. Once set up, crypto withdrawals will only be permitted to the addresses included in your **Withdraw whitelist**.
