Git plugin questions

My organization uses Bitbucket for the code base so we are planning to move our SoapUI scripts to a repository in bitbucket. I have few questions on the ReadyAPI Git plugin:

 

1) When I ever I try to share the project or commit changes it asks to enter bitbucket username/password everytime. How do I avoid that?

2) When the project is checked in it sends the user name as "John Doe" and not my actual name. How do I change the name?
