<p>The present invention relates to a method for providing multi-channel authentication by using a one-time password card, executed by a server capable of communicating with user terminals through a first channel and communicating with wireless user terminals through a second channel which is different from the first channel. The method 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 the wireless user terminals, capable of communicating through the second channel and which will be interfaced with a user′s designated card, based on the authentication request information; a third step of receiving a one-time code dynamically produced through a chip of the designated card which is interfaced with the checked wireless user terminals; a fourth step of checking the result of the authenticated one-time code; and a fifth step of providing the authentication result through the designated path.</p> |
