Password and personal data tips

  • The page's own warning: don't use an ID or password you've used on other servers.
  • Never share your login; under the agreement, whatever happens after that is on you.
  • The phone field has no asterisk, so you can leave it blank. Signing up counts as agreeing to BianKO ad and news SMS messages.
  • Keep the item lock password and secret answer separate from your account password and write them down somewhere safe.
  • If you forget your password, the login page has a "Şifreni mi unuttun?" (forgot your password?) link.

Why OTP matters

Every inner page of the site shows a banner recommending the OTP system, and the user agreement says accounts without OTP are the owner's responsibility. In plain terms: lose an account that had no OTP and you can't blame the server. The site doesn't explain how to switch OTP on.

After signing up: client and starting level

The download page's "Details / Links" table is empty right now, with no client link and no system requirements.

BianKO runs a DX11 USKO client and lets you log in up to 3 characters per PC and 6 per IP. Since the 28 April 2025 update, new characters start at level 83.

FAQ

Do I need a phone number to register on BianKO?
No, it's optional. If you add one, use the international format with the country code.
How long can a BianKO password be?
The password field stops at 13 characters. Usernames can go up to 21.
What if I forget my BianKO password?
The link on the login page opens a password reset page. The site doesn't say what details the reset asks for.
Where do I download the BianKO client?
There's no link on the site's download page at the moment. Only take the client from BianKO's own channels.
