How to set up one-time password authentication

Two-factor authentication using one-time password (TOTP authentication)

At our university, we have introduced two-factor authentication (hereinafter referred to as TOTP authentication) using a one-time password based on the time of day in order to ensure identity verification and prevent unauthorized use when using important systems. In this authentication, in addition to the user name and password that the user remembers, a one-time password that can be generated only by the smartphone that the user possesses is used to realize strong authentication.

Attention

With the global spread of COVID-19 infection, there is an increasing possibility of accessing the university information system from home through online lectures and working from home.

When accessing the on-campus information system from outside the university (home etc.), it is necessary to perform more reliable personal authentication, so two-factor authentication using a one-time password is required when logging in.

Please install the one-time password App and register for the university authentication infrastructure system as soon as possible.
