I am installing magento 2 by cloning from github through Git commands and by installing composer. when 'Composer install' command is entered in git, I got the error ,
"the lock file is not up to date with the latest changes in composer.json"
and it asks for authentication for downloading process.I entered the username and password of Github account. The problem is, it is not accepting it as valid credentials. My doubt is that what credentials should be given there? I also tried giving bitbucket credentials.
