Warning: bb4 will never ask for your password by phone or email. If anyone asks for it, it's a scam — contact support immediately.
Forgetting your password happens to everyone. bb4's password recovery process is quick and simple — you'll be back in within just a few minutes.
Click the "Forgot your password?" link on the login page. Enter your registered mobile number or email. You'll receive an OTP — use it to set a new password. The whole process typically takes 2–5 minutes.
Tip: Your new password should be at least 8 characters long and include a mix of numbers, uppercase, and lowercase letters. Avoid reusing the same password across multiple sites.
Enable two-factor authentication (2FA) to add an extra layer of security to your bb4 account. Along with your password, you'll need to enter an OTP sent to your mobile, making unauthorized access virtually impossible.
Even if someone gets hold of your password, 2FA stops them from accessing your account. bb4 strongly recommends that all members keep 2FA enabled — especially those who make regular deposits and withdrawals.
✔ 2FA Benefits: Enabling 2FA brings the risk of account hacking and unauthorized access down to nearly zero. It's completely free.
