UTokyo Account SSO will be available for ECCS Cloud Email (Google Workspace) (From February 20, 2024)

News

Overview

Users of ECCS Cloud Email have used a specific password for ECCS Cloud Email that is different from their UTokyo Account passwords.
However, to simplify password management and to enhance security through the use of Multi-factor Authentication, we have decided to transition to a Single Sign-On for ECCS Cloud Email using the UTokyo Account

Implementation Date

Tuesday, February 20, 2024

Sign-in Procedures

From February 20 onwards, upon signing in to ECCS Cloud Email, once you enter your Cloud Email address on the Google sign-in page, you will be able to complete signing in to the ECCS Cloud Email using your normal UTokyo Account sign-in. There is no need to enter the unique password for ECCS Cloud Email or follow the 2-step verification procedure.
