  1. If you install Xcode, need to turn off credential.helper.
    Credential-osxkeychain will automatically deal with your key.  
    We want to do it manually so we can have more than one key.

     git config --show-origin --get credential.helper  
 file:/Applications/Xcode.app/Contents/Developer/usr/share/git-core/gitconfig osxkeychain   
 vim /Applications/Xcode.app/Contents/Developer/usr/share/git-core/gitconfig
  2. Go to Keychain Access and remove all key in github.com.
  3. Generate ssh key in your .ssh. Suppose we name them id_rsa_kenway and id_rsa_cw.
     ssh-keygen -t rsa -C "your-email-address"
  4. Go to your GitHub page setting -> SSH and GPG keys -> New SSH key, paste the public key.
  5. (Optional) Attach the new key.
     (delete all attached key)  
 ssh-add -D  
      
 (list all attached key)  
 ssh-add -l  
 ssh-add ~/.ssh/id_rsa_aaa  
 ssh-add ~/.ssh/id_rsa_bbb
  6. Touch file name “config” with the following code snippet.
     Host github.com-aaa  
         HostName github.com  
         User git  
         IdentityFile ~/.ssh/id_rsa_aaa  
 Host github.com-bbb  
         HostName github.com  
         User git  
         IdentityFile ~/.ssh/id_rsa_bbb
  7. Set remote node on local folder.
     git config user.name "bbb"  
 git config user.email "bbb@outlook.com"  
 git remote set-url origin git@github.com-aaa:aaa/testkey.git  
 git remote set-url origin git@github.com-bbb:bbb/testkey2.git
  8. Check your GitHub remote.
     git remote -v
