Before logging in, please make sure you have your Tohokudai ID and related information ready.
For students:
Check the necessary information for logging in on the Tohokudai ID confirmation page.
For faculty and staff:
Check the Tohokudai ID notification or similar materials for the necessary information for logging in.
Make sure you can receive TU Mail / DC Mail

Log out (reference)
The initial setting for multi-factor authentication is one-time password by email.
One-time passwords will be delivered to TU Mail / DC Mail, so make sure you can receive email.
For students:
DC Mail login method — Tohoku University Educational Information Systems Online Guide
For faculty and staff:
TU Mail login method — Organization for Innovations in Data Synergy “TU Mail homepage”
Note: Depending on your employment status, TU Mail may not be provided. In that case, please refer to "Cannot receive the one-time password email" on this page.
Please refer to the following materials and log in:
The display language of Microsoft 365 is displayed based on the language settings of the SeciossLink portal.
Please change the settings as necessary.
By registering multiple multi-factor authentication methods, you can log in with another method even if one authentication method becomes unavailable.
For this reason, we recommend setting up multiple multi-factor authentication methods.
In addition, FIDO authentication (such as Windows Hello) allows you to log in smoothly because password input is not required.
For instructions on how to set up multi-factor authentication, please refer to the linked page.
After logging in with your Tohokudai ID, you can access the following systems:
Student Affairs Information System
Budget Implementation Status Inquiry System
Work Time Management System
Faculty and Staff Groupware
Microsoft365 account
The Academic Access Management Federation in Japan (GakuNin)
