About the systems using multi-factor authentication in Nagoya University

Key Point

At Nagoya University, in order to improve security, authentication methods using multi-factor authentication, such as a one-time password (authentication code) with a 6-digit number that changes every 30 seconds, have been introduced in multiple systems.

This multi-factor authentication needs to be set for each account. If account authentication is managed by another system, You need to set each one.

Currently, Nagoya University has introduced multi-factor authentication into the following systems.

CAS (Central Authentication Service)
THERS account
Roundcube for Nagoya University Mail System and Integrated server mail
Multi-factor authentication independently introduced in each system（NSSS）

Therefore, it is necessary to manage multiple multi-factor authentication codes as shown in the image below, and depending on how you use it, you need to register each account with multiple apps.

Authentication app usage example

Overview of each system

CAS (Central Authentication Service)

it is necessary to register multi-factor authentication for the Nagoya University ID in the CAS system.
Many systems in Nagoya University, such as Nagoya University Portal and NUCT, have introduced this CAS authentication method.
The main authentication methods are "Microsoft Authenticator" and "Google Authenticator", which are authentication apps used on smartphones, and "WinAuth (for Windous)" and "Step Two (for MacOS)", which are authentication software used on PCs.

THERS account

it is necessary to register multi-factor authentication for the THERS account in the THERS system.
It is required for systems that use MS365 accounts and will be introduced as the main authentication method at Nagoya University over the next few years.
As authentication methods, there are "Microsoft Authenticator", an authentication application used on smartphones,
and "SMS authentication", "telephone (voice call) authentication", and "email authentication" that use mobile phone functions.

Roundcube for Nagoya University Mail System and Integrated server mail

it is necessary to register multi-factor authentication for the email address in the Roundcube system.
It is used only when accessing Nagoya University mail on the Web.
The main authentication methods are "Microsoft Authenticator" and "Google Authenticator", which are authentication apps used on smartphones,
and "WinAuth (for Windous)" and "Step Two (for MacOS)", which are authentication software used on PCs.

（Multi-factor authentication independently introduced in each system-NSSS等）

It is necessary to register multi-factor authentication for each system for the user.
Multi-factor authentication is performed only when each system is used, and it is separated from multi-factor authentication CAS.
For the authentication method, refer to the regulations and manuals for each system.
