User authentication

Summary of this page

This page explains basic items mainly concerning the configuration of user IDs and passwords for the Educational Information Services at TU, and their management method.

1. User ID and password

1.1 ID and password system

User IDs and passwords for Educational Information Services at TU are configured as shown in the following table.

スライド

User ID Explanation Password
TU ID Random string of alphanumeric characters
Example: ab12345678
TU ID and password
Sub-ID Random string of alphabetic characters Sub-ID and password
Google Workspace ID [String based on name]@dc.tohoku.ac.jp Google Workspace password
Microsoft365 ID [String based on name]@mso.tohoku.ac.jp TU ID and password
  • Some systems use the student number ID instead of the TU ID. Also, systems and services that are provided solely to students belonging to TU, including a specific faculty, department and/or graduate course on a limited basis, may use IDs other than the above.
  • IDs and passwords are lower and upper case sensitive. For example, “ab12cDe” and “Ab12Cde” are treated as separate strings.

1.2 Method of obtaining an ID and password

IDs and passwords, as discussed in Section 1.1, are allocated to all students concurrently with their enrollment into TU. These IDs and passwords can be confirmed using the following methods.

  • TU ID confirmation page (Can be used for a set period only for departments and new graduate students. The access method is noted in the materials distributed when students enroll.)
  • TU ID notification (This is issued to all students, including non-degree students and auditing students.)
  • Integrated Electronic Authentication System (See Section 2 for the access method.)

2. Integrated Electronic Authentication System

2.1 Use of the Integrated Electronic Authentication System

The following tasks can be carried out using the Integrated Electronic Authentication System. (The following is one example. Other tasks can also be implemented.)

  • Confirm TU ID, sub-ID, Google Workspace ID, and Microsoft365 ID
  • Change the TU ID and password, sub-ID, and sub-password

2.2 Accessing the Integrated Electronic Authentication System

Follow the steps below when accessing the Integrated Electronic Authentication System.

When following these steps, pay ample attention to phishing attacks. Carefully check URLs and electronic signatures, etc. to identify whether or not a website is fake.

  • Access the SSO login screen.

  • Log in using the TU ID and TU password. In the event you access the system from off campus, it is necessary to implement two-step authentication, including a one-time password authentication.
  • If authentication is successful, the student portal site will appear. Click on “Integrated Electronic Authentication System” in this portal site. (In the event you cannot find the system, double click on “service” or “auth” icon, which can be found at the top.)

3. Managing the TU ID and TU password
