No, each person may only hold one 666c account. Creating multiple accounts using the same mobile number, email address, or payment method may result in all accounts being permanently closed and any balance being forfeited.

On the login page, click the "Forgot password?" link. Enter your registered mobile number or email address and a verification code will be sent to you. Use that code to set a new password. If you run into any issues, reach out to 24/7 live chat support.
