Whether it's your first time or part of your daily routine, logging in to 3k io is quick and secure. Just follow the steps below.
Click the "Sign In" button on this page or at the top of any page. The login form will appear immediately.
Log in with whichever you used to register – your mobile number or your username.
Enter the password you created when you registered. Passwords are case-sensitive, so watch your capitalisation as you type.
If all your details are correct, you'll be taken straight to your account dashboard in moments.
Right after logging in, you'll see your balance, bonuses, and betting history — dive straight into any game or bet.
Click the "Forgot Password?" tab on the form. An OTP will be sent to your registered mobile or a reset link to your email.
Try logging in with your username – use the one you chose when you registered.
Too many incorrect password attempts may temporarily lock your account. Wait 30 minutes and try again, or contact support.

Every day, thousands of Bangladeshi users log in to 3k io to enjoy their favourite games — some check cricket odds in the morning, others head to Live Casino at night. Signing in is as simple as it is secure. Every login is protected by 256-bit SSL encryption, meaning your data stays completely private in transit.
There are two ways to sign in to 3k io — with your mobile number or your username. Most users go with their mobile number since it's easier to remember. Just use the number you registered with. Your username is also available as an alternative if you prefer.
The most common login issue is a mistyped password. Passwords are case-sensitive, so a Caps Lock left on is a frequent culprit. Click the eye icon next to the password field to reveal what you've typed and reduce mistakes. Similarly, when entering your mobile number, don't forget the leading 0 — use the format 01XXXXXXXXX.
Enabling two-factor authentication (2FA) on 3k io means that at login, alongside your password, an OTP is sent to your mobile. Both are required to access your account. So even if someone knows your password, they cannot get in without your phone. To turn on 2FA, head to your account settings – it's free and takes just 1 minute to activate.
Forgetting your password happens to everyone. On 3k io, there are two ways to recover it. The first is an OTP sent to your registered mobile – this is the fastest option, with the OTP typically arriving within 1 minute so you can set a new password right away. The second is a reset link sent to your email – use this if you provided an email address when registering. The link usually expires within 15 minutes, so once you receive it, reset your password without delay.
You don't need to download a separate app to access 3k io — Chrome or Safari on your mobile gives you the full experience. After logging in, bookmark the page in your browser so you don't have to type the address every time. Android users can tap "Add to Home Screen" in Chrome for an app-like experience — just tap the icon and you'll land straight on the login page.
If you log in and see a zero balance when you had funds before, don't panic. Start by refreshing the page — your browser cache may be showing outdated information. If the balance is still incorrect after refreshing, reach out via live chat. All your transaction records are stored in your account and nothing is ever lost.
Another key habit for logging in to 3k io safely is making sure you're on the correct website. Always check that the address bar shows 3kio.com and look for the padlock icon next to the URL – that confirms your connection is secure. Before logging in via any link shared on social media, take a moment to verify the address carefully, as phishing sites exploit exactly this.
3k io keeps security in place at every step, from login through to transactions.
