Your 4b100 Account Starts Here
Fill in a few details, pick your deposit wallet — bKash, Nagad, or Rocket — and you're in the lobby. Access is subject to your local law and eligible regions.
How We Protect Your Account
Security on a 4b100 account works at a few levels. Your data moves over SSL encryption so login details and wallet information aren't exposed in transit. Identity verification via mobile OTP ties account access to a device you control. We do not store wallet PINs — those stay inside your bKash, Nagad, or Rocket app. Account access from an unrecognised device triggers an additional check automatically.
SSL Encryption
All data between your browser or app and our servers travels over SSL. Your login credentials and payment details are encrypted end to end during every session.
Mobile OTP Verification
Account creation and unrecognised-device logins require a one-time PIN sent to your registered mobile number. This stops unauthorised access even if a password is exposed.
Wallet PIN Stays Yours
We never ask for your bKash, Nagad, or Rocket PIN. Deposits are confirmed inside your wallet app, so your PIN never passes through our system at any point.
Data Protection Practices
Your personal details are held in line with our privacy policy. We do not share account information with third parties outside of what is required for payment processing and account operation.
Get Help With Your Account
If anything in the registration or login flow doesn't go through, there are a few ways to get it sorted without waiting. Live chat is the quickest path for wallet and OTP issues. For account-level questions, the email route gives you a written record of what was agreed.
Live Chat
Available from the help icon on every page. Useful for OTP problems, wallet connection issues, and login queries that need a fast response.
Email Support
Reach out via the contact address listed in your account settings. Good for account verification documents, withdrawal status, and formal account queries.
Account Help Centre
The help section covers common registration steps, wallet linking instructions, and what to do if your OTP doesn't arrive. Check here before contacting support.
What to Expect When You Register
The registration form asks for your name, mobile number, and a password. Once submitted, a one-time PIN is sent to your number — enter it to verify your account. After verification, your account wallet is active and you can load it straight from bKash, Nagad, or Rocket. If you're coming back, the login page uses
the same mobile number and password, with an OTP step available if your device isn't recognised. Our account support team can be reached via live chat for any step that doesn't go through cleanly — check the help icon on the bottom right of any page. Account eligibility depends on your local law and region.

Fund Your Account with Local Wallets
bKash, Nagad, and Rocket are the main deposit routes at 4b100. To add funds, open your preferred wallet app, send to the account number shown on the deposit screen, enter your wallet PIN, and confirm. The deposit appears in your 4b100 account balance once the wallet transaction completes — no international transfer needed, no currency conversion step. For withdrawals, the same wallet you deposited from is the default payout route, and account verification must be complete before a withdrawal is processed.
