Multiple SSH Keys settings for different github account

Create different public key

Create different ssh key according the article See to Generating SSH keys.

$ ssh-keygen -t rsa -C "your_email@youremail.com" -f id_rsa_work

Or:

$ ssh-keygen -t rsa -C "your_email@youremail.com" -f id_rsa_personal

For example, 2 keys created at:

~/.ssh/id_rsa_work
~/.ssh/id_rsa_personal
```bash

Then, add these two keys as following:

```bash
$ ssh-add ~/.ssh/id_rsa_work
$ ssh-add ~/.ssh/id_rsa_personal
```bash

You can delete all cached keys before:
```bash
$ ssh-add -D

Finally, you can check your saved keys:

$ ssh-add -l

Modify the ssh config

Open ~/.ssh/config file:

$ cd ~/.ssh/
$ touch config
$ vim config # please use your favorite editor

Then added something like:

# work account
Host github.com-work
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_work

# personal account
Host github.com-personal
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_personal

Clone you repo and modify your Git config

clone your repo (note "github.com-personal")

git clone git@github.com-personal:work/repo.git repo_personal

cd repo_personal and modify git config

$ git config user.name "personal"
$ git config user.email "personal@gmail.com"

or

$ git config user.name "work"
$ git config user.email "work@gmail.com"

then use normal flow to push your code

$ git add .
$ git commit -m "your comments"
$ git push
