I am Ambrish Awasthi and this codechef account https://www.codechef.com/users/astr0naut belongs to me and last time i used it at 20 Aug 2017, now when i am trying to login , it says
Sorry, unrecognized username or password
and when i see the profile it belongs to someone else . I do not know the person and doesn’t share password with anyone else. I haven’t used any public computer to login in previous month. The password for codechef account is saved in chrome.
