How the mobileTAN system works


1. In order to complete a transaction or registration, a mobileTAN is requested online.

PIN code

2. A multi-digit PIN code is sent to the customer's mobile phone by SMS.

transaction complete

3. The mTAN is then entered online - and the transaction or registration is complete.

2-factor authentication with mobileTAN (c) atms

mobileTAN solutions are particularly secure, because:

  • the mTAN is generated specific to the transaction in question and can therefore only be used for this.
  • in addition to requiring a user name and password for the on-line access, the customer needs to use the mobile phone registered for the purpose also ("two-factor authentication").
  • the mTAN automatically becomes invalid after a certain time and in addition transaction information is sent to the customer.
