In order to localize this message into your language, you will need to add the following code to the 3d Bank secure components template or revert this template back to its default version.
<div id="bankSecureFullAmountAttention" class="bank-secure-full-amount-attention ng-hide" ng-show="showFullAmountAttention">
<t arg0="{{chargeDisplayAmount}}">While you will only be charged {0} for your promotional period, your bank now requires 3D Secure Authentication for all internet payments. That is why we need your authorization to charge the full price for future renewals</t>
</div>

That is why we need your authorization to charge the full price for future renewals".
To add custom CSS to this message, go to the Checkout Style template and override the style of the class bank-secure-full-amount-attention. For example:
