千葉銀行ワンタイムパスワードアプリ is the official one-time password app provided by Chiba Bank for personal customers of their internet banking service.

A one-time password is a disposable password that can only be used once. By using a one-time password, the security of internet banking transactions is strengthened, providing customers with a safer and more secure online banking experience.

To register for the service, simply follow these steps after launching the app:

1. Tap the "One-time Password Registration" button.

2. Enter your contract number and internet banking logon password from your "Telephone Banking Subscriber Card," then tap the "Logon" button.

3. Your registered phone number will be displayed, choose the password notification destination, and answer the call.

4. Enter the password (5 digits) provided during the call to complete the registration.

Please note that registration is required to use the one-time password app. Make sure to review and agree to the "Terms of Use" and "Notes" displayed within the app. The app is free to download and use, but data charges may apply. It is important to protect your personal information by taking precautions such as setting a passcode on your smartphone and securely managing it.
