what password to enter when doing git push?

hey guys. can smb help me out with git? I tried googling but theres no normal and simple answer. the more i read the less i understand.
i did

git push

git push

i get:

banana@dev2:/var/www/lms2$ git push
[email protected]'s password:

banana@dev2:/var/www/lms2$ git push
[email protected]'s password:
