Changing your password

This page explains how to change your password on the Tokyo Institute of Technology Portal.
* We recommend registering your English-letter name reading when you change your default password. See Registering your name reading for more information.

  1. Log in to the Tokyo Institute of Technology Portal. For more information on how to log in to the Portal, see IC card authentication and Matrix authentication.
  2. Once you are successfully logged in, you will see the Tokyo Institute of Technology Portal menu page. Click "Change password". Below is a sample screen (your menu may look different).

  3. (Matrix authentication only)
    If you log in to the Portal via matrix authentication, you will see a prompt asking you to enter your current password. Logging in to the Portal via IC card-based certificate authentication, on the other hand, lets you change your password without having to confirm your current password.
  4. Next, you will see the password change screen. Enter your new password and click "Register".
    * Your password must be 8-14 characters long and contain at least one English letter.
    Supported character types: Half-width alphanumeric characters and half-width symbols.

  5. When your changes are complete, you will see a "Your changes have been completed" message. Click "OK" to return to the Portal menu page. Log in again to make sure that the system has changed your password correctly.

If you have trouble changing your password

If the system fails to change your password, try logging in again with your old password or new password. If neither password works, use an IC card reader to log in via certificate authentication. That will let you change your password correctly. Contact the office or Co-op where you got your Tokyo Institute of Technology IC card if you do not have access to an IC card reader.
