Recommendation of Multi-Factor Authentication and Change in Password Requirements for UTokyo Account

Table of Contents

UTokyo Account has required users to set passwords that are between 8 and 16 characters long and sufficiently difficult to break as a prerequisite for secure use. However, in recent years, the security situation has worsened and there have been numerous cases of users’ identities and passwords being stolen through targeted attacks, phishing attacks, and other means.

Proper password management is no longer sufficient to ensure the security of accounts, and the use of Multi-Factor Authentication (MFA) has become essential.

In order to encourage the use of MFA for UTokyo Account and to ensure smooth use of UTokyo Account, we are making the following changes to the password validity period and the number of characters in the UTokyo Account.
