Step by Step

How to Complete Your 399b Login

Whether you are signing in for the first time or returning after a session break, the 399b Login process is straightforward and takes under one minute on any device.

1
Navigate to the 399b Login Page

Open your browser on any device — mobile, tablet, or desktop — and visit the 399b Login page. The login page is fully optimised for mobile browsers on Android and iOS. No app download is required. Players in Dhaka, Chittagong, Sylhet, Khulna, and Rajshahi can access the platform on Grameenphone, Robi, Banglalink, or Teletalk data connections without issues.

2
Enter Your Credentials

Type your registered mobile number or username into the first field and your account password into the second field. Both fields are required. Your password is case-sensitive, so check that Caps Lock is not active before submitting. If you have forgotten your password, use the password reset option to receive a one-time code on your registered mobile number.

3
Complete Two-Factor Verification

For new device logins and first-time sign-ins, 399b may send an OTP (one-time password) to your registered mobile number for additional security verification. Enter the six-digit OTP in the verification field when prompted. OTPs expire after three minutes. If you do not receive the OTP within 60 seconds, use the resend option. This step helps protect your account from unauthorised access.

4
Access Your Dashboard

Once authenticated, you are taken directly to your 399b account dashboard. From here you can navigate to Live Casino, Cricket Betting, Slots, the Cashier for deposits and withdrawals, your active bonuses, account settings, responsible gambling tools, and the live chat support panel. The session remains active until you manually log out or the session expires after a period of inactivity.

Account Security

How 399b Keeps Your Login Secure

Security is a core part of the 399b account system. Every login session on the platform is protected by multiple layers of technology designed to keep member accounts safe.

256-bit SSL Encryption

All data transmitted between your device and the 399b platform is protected by 256-bit SSL (Secure Sockets Layer) encryption — the same standard used by major international banks and financial institutions. This applies to login credentials, session tokens, deposit and withdrawal requests, and personal account information. The padlock icon in your browser's address bar confirms the connection is encrypted.

OTP Two-Factor Authentication

When logging in from a new device or browser, 399b sends a one-time password (OTP) to the mobile number registered on your account. The OTP must be entered within three minutes before it expires. This two-factor layer means that even if someone has your password, they cannot access your account without also having physical access to your registered Bangladeshi mobile number.

Session Timeout Protection

399b automatically ends inactive sessions after a set period to prevent unauthorised access on shared or public devices. If your session expires, you will be asked to log in again. Players using public Wi-Fi in Dhaka or Chittagong cyber cafes are advised to always log out manually after their session and to avoid saving passwords on shared devices.

KYC Identity Verification

All 399b accounts are subject to Know Your Customer (KYC) verification before withdrawals are processed. Members submit a photo of their Bangladesh National ID card or passport. KYC verification confirms identity, prevents underage gambling, and protects all members against account fraud and impersonation. Most verifications are completed within a few hours during business hours BST UTC+6.

Password Reset via Mobile OTP

If you have forgotten your 399b Login password, the password reset flow sends a one-time code to your registered mobile number. Enter the OTP on the reset page and create a new password of at least eight characters. Passwords must contain a mix of letters and numbers. 399b will never ask for your password via email, live chat, or phone — any such request should be treated as fraudulent.

Device Activity Monitoring

399b monitors login activity across devices and flags unusual access patterns — such as logins from multiple geographic locations within a short period or repeated failed password attempts. If suspicious activity is detected on your account, 399b's security system will temporarily lock the account and notify you via SMS to your registered number. Contact 24/7 live chat support to unlock and secure your account immediately.

Deposits & Withdrawals

Troubleshooting

Common 399b Login Issues & Solutions

Most login problems can be resolved quickly without contacting support. Below are the most common issues reported by Bangladesh players and how to fix them.

Use the password reset option on the 399b Login page. Click "Forgot Password", enter your registered mobile number, and 399b will send a one-time password (OTP) to that number. Enter the OTP on the reset page within three minutes and create a new password of at least eight characters mixing letters and numbers. If you no longer have access to your registered number, contact 399b live chat support with your KYC documents to request a manual account recovery.

399b temporarily locks accounts after a number of consecutive failed login attempts as a security measure. Wait 15 minutes and try again with the correct password. If the account remains locked, contact 399b live chat support — available 24/7 — and the team will verify your identity and unlock the account. To prevent future lockouts, make sure Caps Lock is off when entering your password and that you are using the correct username or registered mobile number.

First, check that your mobile has network signal — Grameenphone, Robi, Banglalink, and Teletalk networks all support 399b OTP delivery. OTPs typically arrive within 30 seconds; if after 60 seconds the SMS has not arrived, use the resend option on the verification page. If you are still not receiving OTPs, ensure the number registered on your 399b account is the active SIM in your handset. For persistent issues, contact live chat support for an alternative verification method.

Try the following steps in order: (1) Check your internet connection — switch between mobile data and Wi-Fi to rule out a network issue. (2) Clear your browser cache and cookies (in Chrome on Android: Settings → Privacy → Clear browsing data). (3) Try a different browser — Chrome and Firefox both work well for 399b on Android devices. (4) Restart your phone. If the page still does not load, the issue may be temporary platform maintenance — check the 399b live chat for a status update from support.

Yes. Your 399b account can be accessed from multiple devices — for example, your mobile phone during the day and a laptop in the evening. However, 399b only permits one active session per account at a time. If you log in on a second device, the first session will be ended automatically. This is a security feature. Do not share your 399b Login credentials with other people — each person must have their own registered account.

Contact 399b live chat support and provide your username and KYC identity document (Bangladesh National ID or passport). The support team can look up the registered mobile number associated with your account and assist you with regaining access. Note that 399b cannot transfer accounts to a different mobile number without full identity verification. This policy exists to protect all members' account security.

After completing your 399b Login, navigate to Account Settings and select the Security or Password section. Enter your current password, then enter and confirm your new password. Your new password must be at least eight characters and include a combination of letters and numbers. 399b recommends updating your password every three months and never reusing passwords from other websites. After changing your password, all existing sessions on other devices will be ended and you will need to log in again with the new password.

Saving login credentials in your browser's password manager is safe on a personal device that only you use. Chrome and Firefox password managers use device-level encryption to store credentials. However, 399b strongly advises against saving your login credentials on shared devices, public computers, or in cyber cafes in Dhaka or Chittagong. On shared devices, always tick "Private browsing" or use Incognito mode, and ensure you log out fully after each session.
