IC card authentication problems

I get a "Cannot display the webpage" error during IC card auth.
Your browser may not have been able to recognize your IC card. Run the certificate management tool to make sure that your IC card reader can read your card properly. Please refer to How to check your IC card.
If your card reader appears to be working normally, restart your browser and try again.
If your card reader does not seem to be reading your card properly, removing and reinserting your card or connecting your card reader to a different USB port can help solve the problem.
I don't remember my PIN code
The office that issued your IC card can reset your PIN. Bring your IC card to the office and have a staff member help you. As access cards do not have photos on them, an access card recipient must also present an identity document (a driver's license or passport, etc.). See the Inquiries page for office contact information.

The system will lock and disable your IC card if you enter the wrong PIN code a certain number of times. To disable the lock, contact the office that issued your Tokyo Institute of Technology IC card.

Matrix authentication problems

When I enter my Account and Password, I get sent back to the Portal top page
Either your account or password is wrong. Account is a student number or staff number which is written on the surface of your IC card.If you forget your password, see I don't remember my password.

If you know your IC card PIN (a 6-digit number), you can reset your password by yourself using a computer with an IC card reader to log in to the Portal via IC card auth. Computers with IC card readers are available for use at the Co-op. If you do not have access to an IC card reader or do not know your PIN, contact the office that issued your card.

Check the expiration date on the back of your IC card to see if the card is still valid. Also check to make sure that the coordinate letters appear squarely inside the appropriate table cells and that the printed side is free of any dirt or smudges that might make the letters difficult to read.

Problems that happen after you log in to the Portal

I only see links to Webmail and the password change function on the menu
Your IC card is expired. Check the expiration date on the back of your card. Contact the office that issued your card if you need to have the card reissued.

This error can occur in Internet Explorer because adding some of the websites that the Portal uses to the list of trusted sites interferes with the transfer of authentication information.
