First-time registration of MFA (Multi-Factor Authentication)
To enhance security, please register your authentication factors for multi-factor authentication.
We strongly recommend registering two or more authentication methods in case of loss or malfunction.
First, register your phone number (recommended)
If you have a smartphone or mobile phone, please register your phone number as your primary authentication factor first.
As long as your phone number remains the same, it can still be used even after changing your device. Registering your phone number is the most reliable way to prevent login issues.
For phone authentication, you can choose between "SMS (Text Message)" or "Voice Call."
Note: Regarding Unavailable Phone Numbers or International Travel
Multiple phone numbers can be registered simultaneously.
International phone numbers are supported; however, depending on the SMS/Voice authentication system used by Okta, verification codes may not be delivered to numbers outside of Japan (+81).
If you do not receive the verification code within approximately 3 minutes, SMS or phone authentication may not be supported for that number.
If you do not have a phone number or cannot use your Japanese number while abroad, please refer to [STEP 2: Additional Setup ] and register two or more authentication factors.
Alternative authentication factors: Biometric Authentication, Okta Verify App, TOTP, etc.
