Using multiple git accounts in a machine

Problem statement: I have two git-hub accounts, one I use for office work and the other is for my personal work. As per the git documentation, I am able to configure them on my machine, but I can access only one at a time. What I need is a way to configure both the accounts in same machine.

Problem Solution: So far I don't have any solution to this problem. But, I have found a work around to this problem. And here it is ...

1. Assumptions: git-account-1, git-account-2
2. Configure git-account-1 in your machine. Follow the git hub docs.
3. Login to git-hub using git-account-1
4. Search for git-account-2
   
5. Click user name link
   
6. Select the repository
   
7. Click on Fork button
   
   
   
8. By default git-account-1 will get read access to the repository
9. Login to git-hub using git-account-2
10. Open the repository link
    
11. Click on Admin button
    
12. Click Collaborators, Search user and Add
