multi-factor authentication (MFA) refers to authentication that combines two or more of the three authentication factors: "knowledge," "possession," and "biometrics."
"Knowledge" → Passwords, PIN codes, security questions, etc.
"Possession" → Mobile phones, hardware tokens, IC cards, etc.
"Biometrics" → Fingerprints, veins, voice patterns, irises, etc.
Setting a strong password is the first measure to protect your account. However, many users still set easily guessable passwords, and even if a strong password is set, if it is reused across multiple services, there is a risk of multiple accounts being compromised through password list attacks. As the number of accounts to manage continues to increase, the reliance on memory for password authentication is reaching its limits.
The main benefit of introducing MFA is that it significantly enhances security. In particular, elements like facial recognition and fingerprint recognition, which can only be presented by the user, and possession elements are difficult to copy or steal, making unauthorized access to accounts by third parties extremely difficult.
This is the newly adopted authentication infrastructure system for keio.jp accounts.
Passwords and multi-factor authentication factors are also managed by this system.
This app is used for multi-factor authentication (user verification) within the Okta system.
It is used to approve logins and generate authentication codes.
This is a password-free authentication feature that uses the Okta Verify app.
By utilizing biometric authentication methods—such as facial recognition or fingerprint recognition—registered on your device,
you can skip the hassle of entering a password and sign in more securely and smoothly.
This is a disposable authentication code (one-time password) that is updated at regular intervals.
You complete the second step of identity verification by entering the numbers displayed in the various apps that generate TOTP codes.
