  →STEP2-4. When the authentication factor is not registered

When "Your client certificate is invalid. In addition, One Time Password (OTP) factor is not registered." is displayed, one-time password authentication device is not registered.
Even if the device is displaying the 6-digit OTP, the last steps of registration may have been forgotten or deleted after registration.

→STEP2-4. You do not have an authentication factor

If you have a digital certificate, you can use it for JAIST-SSO authentication by importing the digital certificate into your browser.
 

When "Your client certificate is invalid. In addition, One Time Password (OTP) factor is not registered." is displayed, either the certificate has not been imported or there is a problem with the selected certificate.

First, check to see if the digital certificate has been imported into your browser.

Access user's manuals by UPKI from the following page and refer to "Checking the Certificate (PKCS#12 file)".
→User's Manuals for Installation in Different Web Browsers

Is the digital certificate of "...@jaist.ac.jp" imported into your browser?

• Yes, the certificate was imported.
  →STEP2-3-1. The digital certificate has been imported.

• No, the certificate was not imported.
  If you have a digital certificate file→Procedure for importing a certificate

Please check the following points about the imported digital certificate.

• Is the certificate issued after December 25, 2020?
  Certificates issued on or before December 24, 2020 will not be available after January 17, 2022.
  Please refer to the following announcement for details and action.
  →[Important] Client certificates will be revoked (for issued before 2020/12/24)
  
  
• Is the certificate valid?
  Please make sure that your digital certificate has not been revoked.
  →How to check the validity/revoked of the client certificate
  
  
• Have you selected a valid certificate (if you have more than one certificate)?
  If two or more certificates have been imported, the old certificate may be used for authentication.
  →Select the certificate to be used for JAIST-SSO

If you have a One Time Password (OTP), please cancel the certificate selection and try to authenticate with OTP.

If you cannot login
  →STEP3. Unable to log in

Authentication from off-campus requires authentication factors other than username and password (one-time password, client certificate, etc.). When "Your client certificate is invalid. In addition, One Time Password (OTP) factor is not registered." is displayed, it means that the authentication factor is missing.

Please come to the campus and get one (or both) of the following authentication factors.

• Registering a one-time password
  →One Time Password authentication device registration procedure
• Issuance of digital certificates
  →Client certificate issuance procedure
