Additional Setup Guide (Biometric Authentication - Android)

You must register your biometric authentication on your device (Android) in advance.

1. Multi-Factor Authentication (MFA) Setup (Google Password Manager)

*When registering, the account will be linked to the Google account currently logged into your browser.

Please ensure beforehand that you are logged in with the account you wish to register.

On Android devices, the Google account registered to the device will take priority.

If you register using a keio.jp Google account, please be aware that once you log out, you will be unable to authenticate without an additional authentication factor.

Please refer to the descriptions provided either to the right of or below the images for an explanation of each step

1.1. Access the Multi-Factor Authentication (MFA) settings page

Access the Multi-Factor Authentication settings page( https://keio.okta.com/enduser/settings )on your smartphone's browser and log in with your keio.jp account (ID and password).

1.2. Under "Security Method," click "Set up" in the "Security key or biometric authenticator" section.

*When registering, the account will be linked to the Google account currently logged into your browser.

Please ensure beforehand that you are logged in with the account you wish to register.

On Android devices, the Google account registered to the device will take priority.

If you register using a keio.jp Google account, please be aware that once you log out, you will be unable to authenticate without an additional authentication factor.

1.9. MFA settings page in your browser (Security Methods)

Once authentication is successful, the screen will automatically transition, and the authentication factor will be registered.

We recommend setting a nickname so you can easily distinguish between your accounts and devices.

Please Note:

It is possible to register multiple passkeys for the same device or account.
If you delete the most recent passkey, you will no longer be able to log in, even if the setting still appears to be active.
When deleting a passkey, please check the registration date and time of the security methods on the multi-factor authentication (MFA) settings page, and ensure you only delete the older entries.
