Access your 399bet3 account and enjoy Sports Betting, Live Casino, lottery, and more — just enter your mobile number and password.
Enter your registered mobile number and password.
Logging in to 399bet3 only requires two things — your mobile number and password. It's so straightforward that even first-time users can access their account within a minute.
On the mobile app, enabling the "Remember me" option means you can log in next time using your fingerprint or face — no need to type your password. It's faster and more secure.
On your personal device, feel free to enable "Remember Me." Never use this option on a public or shared device.
Logging in to 399bet3 means getting full access to Bangladesh's top betting platform.
The login process at 399bet3 is designed to be as quick and simple as possible. Since you register with a mobile number, there's no email to remember — a particularly convenient setup for users in Bangladesh.
A common question is whether you can log in from multiple devices — and the answer is yes. Whether you're on a mobile phone, tablet, or computer, you can access 399bet3 from any device and your account stays fully in sync. Your balance, betting history, and bonuses are all synchronized across devices.
399bet3 uses multiple layers of security to protect your account. First, passwords are always stored encrypted — they can never be read in plain text. Second, logging in from a new device triggers an OTP verification step. Third, entering the wrong password several times in a row will temporarily lock the account, blocking unauthorized access attempts.
Forgetting your password is completely normal. Resetting it on 399bet3 is straightforward — click "Forgot Password?" on the login page, and an OTP will be sent to your registered mobile so you can set a new password. The whole process takes no more than 2–3 minutes.
The first thing you should do after logging in is go to your account settings and enable two-factor authentication (2FA). It might feel like an extra step, but it significantly strengthens your account security — even if someone gets hold of your password, they won't be able to log in without the second factor.
After logging in, take a moment to check the current bonuses and offers page. 399bet3 regularly runs reload bonuses, free bets, and cashback promotions — these aren't visible without logging in, and many offers are time-limited, so don't miss out.
Avoid logging in on public Wi-Fi. Always log out when you're done. Never share your password — 399bet3 staff will never ask for it.
