i have forgotten my user id of kcet application 2020

Hello there,
You can find your username in your registered email. They must have sent you the username and the password during the verification process. Kindly check the inbox of your registered email and phone number. Check the spam folders too. Still if you can't find it, you can contact the authorities at their helpline number present in their official website.
Hope this information helps you.
Good luck!!
