To reset your password on Kik, you'll need access to the email address registered to your account.
If you can't remember the email address registered to your Kik account, try entering all of the emails you have on our password reset website (ws.kik.com/p). You'll see a success message on screen when you submit an email that matches an account on Kik. That's the email address you'll need to check for the password link from us :)
If you're having trouble accessing your email account, try getting in touch with your email provider's support team.
