OneTimePass calculates a new password for each dial-in or login, which the system only accepts once. With this procedure, with so-called one-time passwords, common attack methods that are often successful with conventional password-based access control mechanisms lead nowhere.

Every user of the system is provided with a so-called token (authentication medium). This token generates the one-time password. It can be operated offline, i.e. without connection to a computer. The user uses the standard login mask of the target application known to him. Here he enters his user ID and the one-time password generated by the token. OneTimePass checks the one-time password and sends the result of the check back to the server or the server application. Communication takes place via the standard RADIUS protocol or SOAP. undefined
