The invention relates to a method and to a device for the authorization in data transmission systems employing a transaction authorization number (TAN) or a comparable password. According to a first step, the user sends a qualifying identification of the data input apparatus together with a request for the generation or for the selection of a transaction authorization number TAN or of comparable password from a data file from the data input apparatus to an authorization computer. In a second step the authorization computer generates the transaction authorization number TAN or the comparable password or selects them form a data file. According to a third step, the authorization computer sends the transaction authorization number TAN or the comparable password over a second transmission path different from the first transmission path to a monitor, for example a pager. According to a fourth step, the user reads this transaction authorization number TAN or the comparable password from the receiver and enters the transaction authorization number TAN or the comparable password into the data input apparatus. According to a fifth step, this transaction authorization number TAN or the comparable password is transmitted to the authorization computer. According to a sixth step, the authorization computer verifies the validity of the transaction authorization number TAN or of the comparable password in order to establish or switch free, according to a seventh step, a connection between the data input apparatus and the receiver unit.
