Mastercard® SecureCode™ will become Mastercard® Identity Check™

Top-level security for your credit card payments on the internet – on April 19, 2019 we have launched Mastercard® Identity Check™, a new identification process checking your identity as cardholder when you use your credit card for online payments. 

With this new identification process you can approve online payments via an app (by fingerprint, face recognition or PIN) or by entering a mobileTAN via text message. In the context of rebranding, Mastercard® SecureCode™ will be replaced by Mastercard® Identity Check™.

If you have any questions when registering for the Mastercard® Identity Check™ please do not hesitate to contact the cardholder service hotline: +49 69 793 325 55 available 24/7.

To allow a smooth transition from the former Mastercard® SecureCode™ process with  mobileTAN to the new 3D Secure process the registration data of the cardholders will be migrated to the new service provider. So cardholders registered for mobileTAN can make their internet payments as usual.
