<p>The present invention relates to a method for providing multi-channel authentication by using an OTP token, executed by a server which is capable of communicating with a user terminal through a first channel and communicating with a wireless user terminal through a second channel. The method for providing multi-channel authentication comprises: a first step of receiving authentication request information requesting multi-channel authentication through a designated path including the first channel; a second step of checking wireless user terminals which are capable of communication through the second channel, based on the authentication request information; a third step of receiving a one-time code inputted through the wireless user terminal by being produced dynamically in a user′s OTP token; a fourth step of checking the authentication result of the one-time code; and a fifth step of providing the authentication result through the designated path.</p> |
