Keep Your Account Secure

  • Use a Strong Password

    Combine uppercase letters, lowercase letters, numbers, and symbols. Avoid using your mobile number, birthdate, or common words. Change your password every few months to stay protected.

  • Enable Two-Factor Authentication

    Add an extra layer of security by linking your account to your mobile number. You will receive a verification code via SMS each time you log in from a new device.

  • Never Share Your Login Details

    3e331 will never ask for your password via email, SMS, or phone call. If someone claims to be from our team and requests your login information, report it to [email protected] immediately.

  • Avoid Public WiFi

    Log in only from secure networks. Public WiFi at cafes, bus stations, or shopping malls can expose your credentials to hackers. Use mobile data or a trusted home network instead.

  • Log Out After Each Session

    Always click the logout button when you finish playing, especially on shared or public devices. This prevents others from accessing your account and balance.

Login Problem? Here's the Fix

Problem Cause Solution
Wrong password error Caps Lock is on, or you typed the password incorrectly Check that Caps Lock is off. Try typing your password in a text editor first to see what you are entering. If you still cannot log in, use the forgot password link below the login form.
Account not found You entered the wrong mobile number or username Double-check your mobile number format. It should start with 01 and have 11 digits total. If you used a username, make sure there are no extra spaces. Contact [email protected] if the issue persists.
Verification code not received Your mobile network delayed the SMS, or you entered the wrong number Wait 2 minutes and check your inbox again. Make sure your phone has signal. Request a new code if needed. If you still do not receive it, try logging in from the app instead.
Account locked Too many failed login attempts in a short time Wait 15 minutes before trying again. This security measure protects your account from unauthorized access. If you did not attempt these logins, reset your password immediately.
Page keeps refreshing Browser cache issue or outdated cookies Clear your browser cache and cookies. On mobile, try switching from WiFi to mobile data. If the problem continues, download the 3e331 app for a smoother experience.
Logged out automatically Session expired after inactivity For security, we log you out after 30 minutes of inactivity. Check the remember me box when you log in to stay signed in on trusted devices. The app keeps you logged in permanently.

Login Questions Answered

Can I log in using my email address?

No, 3e331 requires your mobile number or username for login. We do not support email-based login because mobile verification is faster and more secure in Bangladesh. If you registered with a mobile number, use that same number every time you log in.

Why does the site log me out automatically?

For security, we end your session after 30 minutes of inactivity. This protects your account if you forget to log out on a shared device. To stay logged in longer, check the remember me box when you sign in. The 3e331 app keeps you logged in permanently unless you manually log out.

What should I do if someone else logs into my account?

Change your password immediately using the forgot password link. Then contact our support team at [email protected] and report the unauthorized access. We will review recent login activity and help secure your account. Enable two-factor authentication to prevent future breaches.

Can I use the same account on multiple devices?

Yes, log in from your phone, tablet, and computer using the same credentials. Your balance and game history sync across all devices. However, you can only be logged in on one device at a time—logging in elsewhere will end your previous session automatically.

How do I enable biometric login on the app?

Download the 3e331 APK and log in once with your mobile number and password. Go to Settings inside the app and enable fingerprint or face unlock. From then on, you can open the app and authenticate with your biometric instead of typing your password every time.

What happens if I enter the wrong password too many times?

After five failed attempts within 10 minutes, we temporarily lock your account for 15 minutes. This prevents brute-force attacks. Wait for the lockout period to expire, then try again. If you genuinely forgot your password, use the forgot password link instead of guessing repeatedly.
