CCD2 2FA readiness guide, Magento 2 v4.1.0, and Klarna sandbox testing

August 10, 2026

CCD2 2FA readiness guide

As part of CCD2, the revised EU Consumer Credit Directive, Unzer is introducing an additional risk-check authentication step during checkout for Buy Now Pay Later transactions (Unzer Invoice, Unzer Installment, and Unzer Direct Debit).

The new CCD2 readiness section explains what is changing and why, and includes an interactive readiness check that asks a few questions about your integration and tells you what to change, how to test it, and how to go live.

Magento 2 v4.1.0

We have released Magento 2 plugin version 4.1.0, available as of August 8, 2026, now supporting shop versions 2.4.7 - 2.4.9.
