Sign Into Your bk4 Account
Your bk4 account holds your wallet balance, active promotions, and payment history — sign in to pick up exactly where you left off. Access is available from any mobile browser or desktop, with your bKash, Nagad, and Rocket deposit records all in one place.
What to Expect When You Sign In
Opening the login page on bk4 brings you straight to your email or phone number field, followed by your password. If you have two-step verification active, a one-time code is sent to your registered mobile number — enter it within the time shown on screen and your account loads. From there, the lobby is one
tap away: your wallet balance sits at the top, recent transaction history is under Account, and the deposit section shows your linked payment methods. Returning from a mobile browser on Android or iOS, the session typically resumes without asking you to log in again unless you cleared your cache or switched networks. If you've forgotten
your password, the reset link on the login page sends a recovery code to your registered number. Keep your account number or email handy — that's the fastest path back in.

Manage Deposits After You Log In
Once you're signed in, the deposit section shows your active payment options for Bangladesh. bKash, Nagad, and Rocket are all available — open your wallet app, send to the account number displayed, confirm with your PIN, and the balance reflects on your bk4 wallet. Withdrawals follow the same verified channel you used to deposit, so keeping your payment number current in Account Settings matters. If your Nagad or Rocket number changes, update it before requesting a withdrawal to avoid a verification delay.
How We Protect Your Account
Your bk4 account is protected at every point in the login flow. SSL encryption covers the connection between your browser and our servers, so your credentials and wallet data are not exposed in transit. Identity verification is required before any withdrawal is processed — this step confirms that the account belongs to you and that the withdrawal goes to your registered payment channel. Session tokens expire automatically after inactivity, and any login from an unrecognised device triggers an additional verification step. We do not store your bKash or Nagad PIN — those stay within the respective wallet apps.
Every login session runs over an encrypted connection. Your password and account data are protected from the moment you submit the form.
Withdrawals require identity confirmation tied to your registered details. This step protects your wallet from unauthorised payout requests.
A login from a new device or browser triggers an extra verification step before access is granted, reducing unauthorised entry risk.
Your bKash, Nagad, and Rocket payment details are stored only as references to your registered number — never as raw credentials on our side.
