I can't log in

TL;DR

The simplest way: on the sign-in screen, enter your e-mail address and tap “Send my code”, then enter the six-digit code you receive by e-mail. You can also “Continue with Google”. If you use a password and it's rejected, check the address and what you type: after 5 failures, signing in with a password is blocked for 15 minutes. If nothing works, write to support@ktkarena.com.

The three ways to sign in

1. A code by e-mail. Enter your e-mail address, tap “Send my code”, then enter the six-digit code you receive (“Enter your code” screen).

2. Google. Tap “Continue with Google”.

3. Your password, if your account has one (Settings → Security → “Password” tells you). If two-factor authentication is on, the app then asks for the code from your authenticator app or a backup code.

Your account has no phone number: none of these methods asks for one.

The code doesn't arrive or is rejected

  • Check the address you entered (tap “Edit” on the code screen) and your spam folder, then tap “Resend the code”.
  • If the code is reported as incorrect: retype the last code you received, only the last one requested is valid.
  • If the code has expired or there were too many attempts: ask for a new code.

The password is rejected

  • The app shows the same message whether the address or the password is wrong: check both.
  • The password is case-sensitive: the eye icon shows it while you type. Watch out for keyboard suggestions too.
  • After 5 failures, signing in with a password is blocked for 15 minutes, with the same message. The e-mailed code still works.
  • Forgot your password: you don't need it to sign in, see I forgot my password.

When to write to support

Write to support@ktkarena.com if you no longer have access to your e-mail address, if you think someone else is using your account, or if nothing works. Give your username and describe what you see. No reply time is guaranteed.

FAQ

Frequently asked questions

Yes: each device has its own session. Changing your password signs them all out.

Your account doesn't have one: you sign in with your e-mail address or with Google.

No: your ongoing challenges carry on without you and resolve normally.
