Git Bash asking for my user credentials when performing a push using SSH

I have created and successfully implemented a Git project on the Codaset website. I am using SSH to communicate between my Codaset and my local repository. When I do a push from Git Bash, Git Bash asks me for my user name credentials. Although, Git Bash performs the push successfully, it is tedious to having to enter my user credentials every time I perform a push.

I have checked out many blogs and suggestions to fix this problem, but to no avail. Also, I have tried to use PuTTY. My questions are:

1. How can I fix this problem?
2. Or, can I turn on some debugging to at least identify the precise reason(s) why Git Bash is asking for my user credentials?
