After your coach adds you to a team, you get an e-mail with the required details which include the useername(which is the same as your registered e-mail id)and a link to set your password 
Last year, each team had only one account, the details of which were sent by CodeChef to every team member on his/her email. Received it 2-3 days before the contest date. Also a practice round test was conducted by CodeChef to make teams familiar with the contest platform.
