Accidentally disconnect my codechef account from github

I have registered into Codechef using a Github account. I wanted to log out for some reason so I have clicked on the GitHub symbol on the top right corner of the Codechef page. My chrome browser asked me ‘are you sure you want to disconnect GitHub’ and I have clicked ‘OK’.
Now CodeChef is asking for new registration.
I was at 2 star rating. How can I get my account back?
Please please help!


I hope you remember your username.
So, just enter your username and github password, if you remember. Else, do forget password. They would send you reset link in the email id connected to your github account.

It worked! Very happy to see my profile back.
Thank you very much bro!
