Login Security – How 40a Keeps You Protected

Every login session on 40a is secured with SSL/TLS encryption. Your username and password are never transmitted as plain text — everything is encrypted so no one can intercept it along the way.

40a also uses an automated suspicious login detection system. If a login attempt is made from an unknown device or unusual location, you'll get an instant alert on your mobile.

Three consecutive incorrect password attempts will temporarily lock your account and you'll be notified on your mobile. This protects your account from hacking.

AES-256 Encryption
Passwords & data protected with military-grade security
Zero-knowledge password

What to do if you have login issues

Click the "Forgot password?" link on the login page. Enter your registered mobile number or email and a password reset link will be sent to you. Alternatively, you can log in directly using OTP.

Three incorrect password attempts will lock your account for 30 minutes. Try again after that period, or contact support — our team will verify your identity and unlock your account right away.

Please check your network connection first. The "Resend" button will appear after 30 seconds. If you still don't receive it, try logging in via email or contact us on Live Chat.

Email us immediately at support@40a.bet or reach out via live chat. Our security team will freeze your account right away and restore access securely after verifying your identity.

Log in with your email and update your new number in your profile. Alternatively, contact support with your NID and previous account details to change your number.

Important tips for secure login

Follow these guidelines to keep your account secure.

Strong Password

Use a mix of numbers, uppercase, and lowercase letters. Never use "123456" or your own name as a password.

Never share your password

No 40a staff member will ever ask for your password. If anyone does, it's a scam.

Use your own device

Avoid logging in from public computers or someone else's phone. Always use your own device.

Check the correct website

Before logging in, make sure the URL shows 40a.bet. Stay alert for phishing sites.

Avoid public WiFi

Avoid logging in over free Wi-Fi at tea stalls or bus stations. Use your own mobile data instead.

Change your password regularly

Change your password every 3 months. Never use the same password across multiple sites.
