If you have forgotten your KCET user ID and password you can start by checking your email ID for it or any other place where it might be. If you still are unable to find the user ID and the password you can contact the KCET officials and email them regarding your issue at their official email address. You can email them your issue and ask for assistance at the following -

I hope this helps.

All the best!!
