DNB Authenticator Go is more now … DNB Authenticator Go still provides you with 2-Step Verification. This means a stronger security for your DNB Luxembourg Account by requiring a second step of verification when signing in. The DNB Authenticator Go now adds Strong Customer Authentication for PSD2. This includes authentication with the camera of your mobile device. The new payments feature makes it easy and secure to authorize orders and payments. Before a transaction is authorized, a QR code is displayed. Just scan the code in your DNB Luxembourg app. This immediately generates a transaction number that you can use to release the order.
