Log In to Your 644jj Account
Your 644jj account is where your bKash, Nagad, or Rocket wallet connects directly to the lobby — enter your registered mobile number, confirm the OTP, and you are inside. Access depends on your local law and eligible region in Bangladesh.
What to Expect When You Sign In
Open 644jj on your phone or desktop browser and enter the mobile number you used when creating your account. A one-time password arrives via SMS — enter it to confirm your identity. If this is your first time, the account creation form asks for the same mobile number plus a password you choose; the OTP
step runs there too. Once inside, your wallet balance, transaction history and lobby shortcuts are all on the same screen. If you have forgotten your password, the reset link on the login page sends a fresh OTP to your registered number so you can set a new one without contacting anyone. Keep your login details
private and log out after each session on a shared device.
-
OTP Verification Every login is confirmed by a one-time password sent to your registered mobile number, so only you can access the account even if someone has your password.
-
Password Reset Path Forgot your password? Hit the reset link, enter your registered number, and a fresh OTP lets you create a new password without waiting for support.
-
Wallet Ready After Login Your bKash, Nagad, or Rocket deposit balance shows immediately after login — no extra navigation to find your funds or pending transactions.
-
Account Support Channel If your OTP is not arriving or your account is locked, our Bangladesh support team can be reached via live chat directly from the login page.

How We Protect Your 644jj Account
Your account and wallet details sit behind multiple protection layers. Every login session runs over an encrypted connection so data moving between your phone and our servers cannot be intercepted. Identity verification through OTP means account access is tied to the physical SIM registered with us — not just a password. We do not store your bKash, Nagad, or Rocket PIN at any point; those stay inside your wallet app. Your data is handled according to our privacy policy, and you can review or update your account details from the profile section after login.
SSL Encryption
All data between your browser or app and 644jj travels over an SSL-encrypted connection, keeping your login credentials and session details away from third parties.
OTP Identity Check
The OTP step ties every login to your registered SIM card. Even if a password is compromised, the account cannot be accessed without the code sent to your phone.
No Wallet PIN Storage
We never see or store your bKash, Nagad, or Rocket PIN. All wallet transactions are authorised entirely within your own wallet app, not on our side.
Data Privacy Controls
Your personal and account data is handled under our privacy policy. You can review, update or raise a data query from the profile section once you are logged in.
Deposit and Withdraw After You Log In
Once you are logged in, the cashier section shows your local payment options in one row. Sending money through bKash means opening your bKash app, entering the account number shown on the 644jj cashier screen, and confirming with your PIN — the balance updates shortly after. Nagad works the same way through its own app, and Rocket follows the same send-and-confirm flow. Withdrawals reverse the path: enter the amount, choose your wallet, and the funds are sent back to the same bKash, Nagad, or Rocket number you deposited from. Availability depends on local law and eligible regions.
