GitHub: Multiple account setup

Question

I am trying since more than 3 hours to setting up multiple account for github and litteraly tired. I have tried out almost all possible way describe here, github and article

Answer 1

So according to @VonC's answer here what I have done.

1. I have generate ssh key for another account and added with id_rsa_ac2 (where ac2 is for second account)
2. Than just cross checked either it works with ssh -T ac2.github.com
3. Created config file (without extention) in /c/Users/yourname/.ssh/ directory

Here is the code what I used for config file

#Account one
Host github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile /c/Users/yourname/.ssh/id_rsa
    User git

#Account two
Host ac2.github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile /c/Users/yourname/.ssh/id_rsa_ac2
    User git

So now once you done this you can start to use both account as you need.

for main account I added remote as origin with git remote add origin git@github/youraccount/rep.git Than to push use git push origin master this will upload to your first account.

To add remote for second (ac2) account used git remote add ac2 ac2.github/yoursecondaccount/rep.git Than to push use git push ac2 master this will upload to the second (ac2) account.

To check if it has added remote use git remote -v and incase if you want to remove anyone than use git remote rm origin where origin is your added remote.

Hope this information will helps to other who is having the same issue.

Thanks again to @VonC
