Open Your But 999 Login in a Few Steps
Signing in starts with the mobile number and password you set at registration, and a one-time OTP confirms new devices before the session opens.
See How We Protect Your Login Details
Account safety on But 999 starts with the same login you use every day, not a separate security layer you have to think about. Passwords and OTP codes travel over encrypted connections, and identity checks run quietly in the background before a withdrawal is approved rather than after money has already moved. We don't publish exact detection thresholds, since that would tell us as much to bad actors as to you, but repeated unusual sign-in attempts do get flagged and reviewed on our side.
Every login session between your device and our servers runs over an encrypted connection, so your password and OTP code aren't sitting in plain text as they travel.
Before a first withdrawal clears, we confirm the details on your account match the wallet you're paying out to, which protects your bKash, Nagad or Rocket balance from mismatched transfers.
Your registered number, password and transaction history are stored under account-level access controls, limiting who inside our support team can view your full profile.
We watch for repeated failed login attempts on an account and can pause access temporarily, which is a safeguard rather than a lockout you should expect on normal use.
Check What Happens After You Sign In
Opening a But 999 account starts with your mobile number, a password you set, and a fixed PIN you'll use again at withdrawal time. When you sign in from a new device, we send an OTP to the same number linked with your bKash, Nagad or Rocket wallet, so the code and your payment method
sit under one profile. That link matters later: once you're logged in, the deposit chip row already knows which wallet you last used, so returning to fund your account before a Baccarat Jungle table or an Aviator round takes fewer taps. If you forget your password, the reset flow asks for the same number and
a fresh OTP rather than an email chain, which keeps recovery inside the wallet-linked profile you already trust. We also flag sign-ins from a browser or device we haven't seen before, asking for a second confirmation step.
-
Mobile-Number Verification Every sign-in ties back to the mobile number you registered, confirmed by OTP rather than a static password alone, so a stolen password on its own can't open your wallet-linked profile.
-
PIN-Protected Withdrawals The withdrawal PIN you set at registration stays separate from your login password, giving your account a second gate before any payout request reaches processing.
-
Device Recognition Checks Signing in from a browser or handset we haven't seen triggers an extra confirmation step, which keeps casual access attempts from strangers away from your bKash, Nagad or Rocket-linked balance.
-
Direct Lobby Return Once you're through, the account remembers your last-used payment method and recently opened tables like Baccarat Jungle or Football League Special, so you're not hunting through menus again.

Bring bKash, Nagad or Rocket Into Your Login
Your login and your wallet sit closer together than you might expect — the same mobile number that gets your OTP is often the one behind your bKash, Nagad or Rocket account, so signing in and topping up feel like one motion instead of two separate errands. We don't ask you to re-enter payment details every session; once a wallet is linked, the deposit screen remembers it. Withdrawals route back to that same verified number, which is one reason we ask you to keep your registered mobile consistent across sign-ins.
Reach Support If Sign-In Fails
Not every sign-in goes smoothly on the first try, and that's fine — a wrong OTP entry, an expired session, or a password you haven't used in a while can all stall you at the door. We keep more than one published channel open for exactly this, so you're not stuck refreshing the same login page. Whichever route you pick, having your registered mobile number and the wallet you used for your last deposit ready speeds up how support can confirm it's actually your account.
