Multi-Factor Authentication for UTokyo Accounts

You are required to enable multi-factor authentication on your UTokyo Account to use the UTokyo Wi-Fi for security reasons.

• Before using the UTokyo Wi-Fi, you must complete the initial setup for Multi-Factor Authentication on your UTokyo Account. Please refer to the “Initial Setup Procedures for Multi-Factor Authentication for UTokyo Accounts)” for specific instructions.

Information Security Education

UTokyo Wi-Fi is only available to users who have completed the Information Security Education. The Information Security Education is held annually for all UTokyo Account holders with the aim of improving Information Security at UTokyo. For details about the timing and the procedure of the course, kindly refer to the Information Security Education page.

Using UTokyo Wi-Fi on Shared Devices

UTokyo Wi-Fi is only available on individuals’ own device: it is prohibited to use UTokyo Wi-Fi on a shared device by more than one person. Because it allows anyone other than the user who owns a UTokyo Wi-Fi Account to use the service, and it is considered to be lending of an account, which is prohibited by the Terms of Use. However, if the OS user account is set up separately for each individual, and the UTokyo Wi-Fi account can only be used by the person who has obtained it, UTokyo Wi-Fi is able to be used.

Steps to start using the service

Preparation: Apply for a UTokyo Wi-Fi Account

In order to use UTokyo Wi-Fi, a UTokyo Wi-Fi account must be issued each academic year. In this “Step 2”, we will explain the procedure for applying for a UTokyo Wi-Fi account.

You can apply for your own account using the “UTokyo Wi-Fi Account Menu”. The user ID and password for your account can be viewed on the “UTokyo Wi-Fi Account Menu” screen only immediately after submitting application, and you will also be notified by email. Please note that you can use your issued UTokyo Wi-Fi account to connect to UTokyo Wi-Fi on multiple devices.

1. Access the “UTokyo Wi-Fi Account Menu” below.

2. Unless you have already signed in to your UTokyo Account, the sign-in page will be displayed. Please sign in.UTokyo Wi-Fi Account Menu Help: When the error message “You don’t have access to this” (Error Code: 53003) appears

It is possible that the setup or activation of the multi-factor authentication (MFA) for your UTokyo Account, which is required to use the UTokyo Wi-Fi, has not yet been completed. Please make sure to follow the initial setup procedure on the page, “Initial Setup Procedures for Multi-Factor Authentication for UTokyo Accounts” until the last step, “Step 4: Apply for MFA Use” to enable multi-factor authentication for your UTokyo Account. It will take about 30 minutes for the MFA settings to be reflected in the system after these procedures, so please wait for a while.

If the issue is still not resolved, please consult the Technical Support Desk.

If you encounter an error message like the one shown in the image below (Error Code: AADSTS50105) and are unable to sign in to the UTokyo Wi-Fi account menu, it’s possible that you have not completed the required information security education to use UTokyo Wi-Fi.

Usage: Connect to UTokyo Wi-Fi

Follow the steps below to connect to UTokyo Wi-Fi.

This process can only be done in the place where UTokyo Wi-Fi (Wi-Fi with SSID 0000UTokyo) is visible on the Wi-Fi setting menu of your own devices.

1. Select 0000UTokyo on the Wi-Fi connection settings screen of the device you want to connect.
2. Enter the user ID and password of your UTokyo Wi-Fi account (not of your UTokyo Account). You can find your user ID and password in the notification email you received in the above 'Preparation'. If you have just finished your application, you can also find them on the application completion screen of the account menu.
3. Once you establish a connection, you can use it just like any normal Wi-Fi.

When connecting, you may be asked to verify your certificate or to enter the information described in the "Connect Configuration" section below.

Please refer to ECCS Tutor’s page as well if you are unsure. There are detailed connection instructions for each device. You may also refer to the “User’s Guide” on the page of the Wi-Fi system called “eduroam”, which has a similar connection method (replace eduroam with UTokyo Wi-Fi SSID when you read the page).

Troubleshooting guide

• If the signal is weak, the connection may be interrupted. Try different locations or times of the day.
• When you enter your user ID, please include the alphabetical part as well.
• Make sure you have entered the symbols in the password correctly. Try copying and pasting from the notification email.
• If you are copying and pasting from a notification email, please make sure that there are no extra spaces before or after the password.
• If you have multiple applications for an account during the process, only one of them will be valid; only the account listed in the UTokyo Wi-Fi account menu will be valid, so please check.
• The trouble may be caused by devices which are not kept up to date. Old MacOS, Windows 8.1 or earlier, and other devices (smartphones, etc.) that have not been updated should be updated to the latest version before connecting.

Procedure by Device Type

Additionally, the following pages provide detailed connection instructions for each type of device.

• Using UTokyo Wi-Fi on Windows

Information on usage

Account expiration date

UTokyo Wi-Fi accounts expire at the early May of the following academic year. New accounts can be issued before the start of each academic year, so if you wish to continue using the service, you must reissue an account each academic year. For details on how to reissue an account, please refer to the “Procedure for reissuing or re-setting up your account”.

If you suddenly lose Wi-Fi connection

If you suddenly lose connection to UTokyo Wi-Fi when it was working fine before, there may be a problem with your UTokyo Wi-Fi account. To check this, try signing in to the “UTokyo Wi-Fi Account Menu”.

• If you receive the error message “申し訳ありませんが、サインイン中に問題が発生しました。” or “Sorry, but we’re having trouble signing you in.” and you are unable to sign in, you may have not passed the confirmation test of the Information Security Education which is conducted annually. In this case, please attend the “Information Security Education” first, pass the confirmation test, and then reissue or re-set up your account.
• If your UTokyo Wi-Fi account information, such as user ID and notification email address, is not displayed on the screen immediately after signing in, your account seems to have been deleted for some reason. Please reissue or re-set up your account.
• The expiration date of your UTokyo Wi-Fi account will be displayed on the screen immediately after you sign in. If the expiration date has passed, please reissue or re-set up your account.

If none of the above applies, there appears to be nothing wrong with your UTokyo Wi-Fi account. It could be due to a temporary fault with UTokyo Wi-Fi or a malfunction with your device. Check the UTokyo Wi-Fi troubleshooting page.

If you still have trouble, please contact Technical Support Desk.

Procedure for reissuing or re-setting up your account

In some cases, a previously used UTokyo Wi-Fi account may become invalid for some reason, such as expiry. In these cases, it is not sufficient to simply reissue an account from the UTokyo Wi-Fi Account Menu; you will need to set up the newly issued account on your device again. Follow the steps below.

1. Re-issue an account from the UTokyo Wi-Fi Account Menu according to step 2 of the “Steps to start using the service”.
2. If the error message “申し訳ありませんが、サインイン中に問題が発生しました。” or “Sorry, but we’re having trouble signing you in.” appears, please take the “Information Security Education” and pass the confirmation test. To pass the confirmation test, you must answer all questions correctly.
3. Follow step 3 of “Steps to start using the service” to re-set up your account on the device.
4. In some cases, the device may store your previous UTokyo Wi-Fi account information and not allow you to change it (i.e., the screen for entering a new user ID and password does not appear). In this case, please delete the UTokyo Wi-Fi account information. The specific procedure for deleting the information varies depending on the operating system and type of device, so refer to the manual of the respective device.

Security measure

The network of UTokyo, including UTokyo Wi-Fi, is secured by UTokyo Campuswide Firewall and other measures to ensure information security.
