Mobile Access in Three Steps
No app store visit needed. The 21 winbd mobile site works through your existing browser, so setup is as quick as opening a link. Follow the steps below to get from a blank browser to a live session. If your browser prompts you to add the site to your home screen, accept it — the shortcut behaves like a native app icon
and opens directly to your account lobby without the address bar. Once you're signed in, your bKash, Nagad, or Rocket wallet details stay saved to your account so repeat deposits take seconds rather than minutes.
- Open 21 winbd — Type the address into your mobile browser or tap a saved link. Chrome and Firefox on Android and Safari on iOS all handle the full lobby.
- Check browser compatibility — The site checks your browser on load. If a feature like biometric login isn't supported by your current browser version, the site will flag it and suggest an update path.
- Sign in securely — Enter your account credentials or use fingerprint login if your device has it set up. An OTP may be sent to your registered number as an added account-security step.
- Add to home screen — Use your browser's share or settings menu to pin 21 winbd to your home screen. From that point, one tap takes you straight into the lobby.
