SSO (Single Sign-On)
Student portal

1.1 Service details

The SSO (Single Sign-On) is one user authentication mechanism for TU information services. This primarily functions as an authentication window when accessing various information services on campus from the off-campus network. In addition, the comprehensive collection of links to various student information services can be used as a login window for the “student portal site.” For some information services, when logging in, users must always go through the SSO authentication regardless of whether accessing from the campus network or from the off-campus network.

In SSO, to boost the security level, in addition to regular authentication using the TU ID and TU password, in certain cases it is necessary to implement the authentication process using a disposable password, referred to as an “one-time password authentication.”

1.2 Users

SSO is available for use by all students at TU (undergraduates and graduates). Procedures, including user registration, are not necessary for use but requires that a student must have a TU ID issued to them.

The student portal site can be used after going through SSO authentication, which is explained on this page.

1.3 Location and method of use

Use when browsing the web. Possible to access from the campus network and the off-campus network.

To receive authentication using SSO, the operating procedures for access from a campus network differ from that of access from an off-campus network.

2.1 Access from the campus network

• Access the SSO login screen.
  
• Log in using the TU ID and TU password.
• If authentication is successful, the student portal site will appear. It is possible to access various campus student information services from this portal site.
  

2.2 Off-campus access

• Access the SSO login screen.
• Log in using the TU ID and TU password.
• After going through the authentication process using the TU ID and TU password, next use a one-time password for authentication. Read the explanation in Section 3 mainly concerning concrete operational methods.
  
• After going through the one-time password authentication process, move to the student portal site screen.

3.1 Summary

In SSO, to boost the security level, in addition to regular authentication using the TU ID and TU password, in certain cases it is necessary to implement the authentication process using a disposable password, referred to as an “one-time password authentication.” One-time password authentication, when connecting from an off-campus network, can be executed after implementing regular authentication using the TU ID and TU password.

3.1 Preliminary preparation

Enable the DC Mail service. View this page or the quick guide on how to use DC Mail and for the set-up method.

3.2 Authentication method

• Select the one-time password (email authentication), click on “Select.”
  
• A one-time password will be sent to your DC Mail. Example: 76110476
  
• Input the one-time password (Example: 76110476), lastly, click on login.
  

3.2.3 Supplemental information

• One-time passwords are random at each time. Consequently, “76110476,” a password configured from the above example, is a “disposable” password only valid for one time. The same “disposable” password will not be valid after two (2) or more uses or after a certain period of time has passed.
