Sign in without your password
- On the sign-in screen, enter your e-mail address.
- Tap “Send my code”: a six-digit code is sent to that address.
- Enter the code in the app. You're signed in.
You can also tap “Continue with Google”. Your account, your balance and your challenges don't change: signing in doesn't touch anything else.
What about your password?
Many accounts don't have one: they were created with an e-mailed code or with Google. In the app, Settings → Security → “Password” tells you whether yours has one.
The app doesn't offer a way to reset a forgotten password. To change it, you need to enter the current one, in the same place; changing it signs all your devices out.
If you've turned on two-factor authentication
When you sign in with your password, the app also asks for the six-digit code from your authenticator app, or one of your backup codes. If you no longer have access to your authenticator app, see I lost my phone with my 2FA.
What can get in the way
The code doesn't arrive. Check the address you entered (tap “Edit” on the code screen) and your spam folder, then tap “Resend the code”.
The code is rejected. Only the last code you asked for is valid, and it expires: the app says the code has expired or that there were too many attempts. Ask for a new one.
Too many wrong passwords. After 5 failures, signing in with a password is blocked for 15 minutes. The e-mailed code still works.
You no longer have access to your e-mail address. Without it, you can't receive a code. Write to support@ktkarena.com from an address you can read, explaining your situation.
