One-Time Password authentication (OTP authentication)

This page will explain how to log in to the Tokyo Tech Portal by using a temporary password. Although you need to perform the initial set-up, you will be able to log in to the Portal without your IC card after that.

Initial set-up

Register an email address, which will receive a temporary password.
(Here we will use an example for registering G-mail address.)

1. Log in to the Portal using the "Matrix/OTP/Soft Token Authentication" or "IC card authentication".
2. Click the "One-Time Password & Soft Token Settings" button which is located under Setting in the menu.
   Note: It is not available to set up One-Time Password authentication using Matrix authentication from off-campus. Please set up from on-campus or using other authentications.
   
3. Enter the same password that you use for Matrix authentication and click the"Authenticate" button.
   
4. Click the "Email" button.
   
5. Fill in the fields "Label" (Japanese label is OK) and "Email" and click the "Add" button.
   
6. A URL will be sent to the email address which you registered. When you click the URL, you will see the image below.
   
7. Click the "List of Contact Email Addresses". When you see your registered email address there, it means you successfully completed the initial set-up.
   

Log-in procedures

1. Select the "Matrix/OTP/Soft Token authentication". Enter your "Account" and "Password" and click the "OK" button.
   
2. Select the "Label" which you registered, and click the "OK" button.
   
3. Enter the temporary password which was sent to your registered email address and click the "OK" button.
   

Procedures to switch from OTP authentication to Matrix authentication

1. If you prefer using the Matrix authentication to using One-Time Password authentication, select the "Matrix" and click the "OK" button.
   
   Note: You cannot give priority to Matrix authentication to log in to the Portal as long as you have a registered email address for OTP authentication. Once you delete all registered email addresses, you can use Matrix authentication only to log in.
