Recently, one of my colleague used my email & name in .gitconfig for pushing the code in master branch (Ethically wrong, but it was mostly for fun). As git takes the name from config, instead of actual ssh or login, rest of them are seeing my name in commit.
As changing config is easy & doesn't require any authentication/authorization. I want to know, is there a way through which I can differentiate actual me from the fake me?
Note: My colleague & I've similar rights to push in repo. Actually, it is same for all the devs in our team. Most of us uses ssh way of pushing in git.
