How to register authentication seeds to each authentication app
Below are the steps to register with some representative authentication apps. Windows users who do not have a smartphone should use WinAuth.
You only need to set up at least one of them, but we recommend setting up multiple devices that you use regularly.
We recommend using Microsoft Autenticator as a smartphone authentication app.
Setup instructions for each authentication app
- (Recommended) Registering the authentication seed to Microsoft Autenticator (smartphone app)
- Registering the authentication seed to Google Authenticator (smartphone app)
- Registering the authentication seed to WinAuth (Windows app)
- Registering the authentication seed to Step Two (macOS app)
In addition, if the authentication app accepts the OATH-TOTP standard (time-based) that updates every 30 seconds, you can use any authentication app other than these (such as iOS's standard feature). However, we cannot support you from Nagoya University.
