Login Alert Notification Service
Login Alert
A notification email is sent to inform you when we detect a login from a new device.
If your JMB membership information and password are stolen and you are logged in illegally, you will be notified immediately with a login alert.
Log in that I don't remember
If you are not familiar with the login you have been notified about, it is permitted that a third party has misused your account. We will inform you to change your password.
Changing Your Password
You can do this via "Change password."
<In the event of an unauthorized login or unauthorized award redemption.>
It is permitted that a third party may have spoofed your registered e-mail account and used your one-time password.
Additional correspondence is required to change passwords for email accounts.
STEP1: Email account management
- Possible to log in to your email account.
- No emails that I don't remember.
- The forwarding address or contact for reassignment is your own.
STEP2: Reset password and device information
- Reset your password (Avoid using the same password over and over again.)
- Set up two-factor authentication for e-mail accounts and register device information.
If you remember logging in yourself
A login alert e-mail will be sent to you when your login environment is different from usual, even if it is your own login.
- When you log in for the first time from a new device (including when you change your device to a new model).
- When you log in from a different browser.
- When you have deleted your cookies or factory reset your device.
- When you link your JMB membership information to a third-party app.
