Information on MobileTAN via SMS
In your interest we are constantly enhancing the security of the 24You Online banking system. The user environment of MobileTAN via SMS has unfortunately changed since its inception more than 15 years ago. Techniques to intercept, read or redirect SMS notifications could now be available to potential aggressors to an extent whereby we can no longer, under all circumstances, guarantee the necessary confidentiality.
In light of this objective security risk we have decided to take the two risk-minimisation measures outlined below. As user of CardTAN or MobileTAN Push via the MobileBanking app you are already using a very safe TAN procedure. The following measures will therefore not affect you.
