# If the TAN list is compromised, the user may cancel it by notifying the bank.
In the Netherlands and Germany, customers of the Postbank can get the TAN codes sent by [[SMS]]. The advantage is that users only get a TAN code when they are initiating a (real) transaction. Several banks use TAN codes sent by [[SMS]] in [[Hungary]] and [[South Africa]].
TANs are believed to provide additional security because they act as a form of [[two-factor authentication]]. Should the physical document containing the TANs be stolen, it will be of little use without the password; conversely, if the login data are obtained, no transactions can be performed without a valid TAN.
