Multiple SSH Keys settings for different github accounts

Create different public keys

Create different ssh keys according to the article Generating a new SSH key and adding it to the ssh-agent

$ ssh-keygen -t ed25519 -C "your_email@example.com"

Please refer to github ssh issues for common problems.

for instance, you have created the following keys:

~/.ssh/id_ed25519_w
~/.ssh/id_ed25519_p

then, add these two keys as following

$ ssh-add ~/.ssh/id_ed25519_w
$ ssh-add ~/.ssh/id_ed25519_p

you can delete all cached keys before

$ ssh-add -D

finally, you can check your saved keys

$ ssh-add -l

copy your ssh key

$ xclip -sel clip < ~/.ssh/id_ed25519_p.pub

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ nano config

Then add

# work account
Host github.com work-login
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_ed25519_w

# personal account
Host github.com personal-login
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_ed25519_p

Clone you repo and modify your Git config

clone your repo git clone git@github.com:perconal-login/repo_name.git

cd repo_name and modify git config

$ git config user.name "work-login"
$ git config user.email "your_work_email@example.com" 

$ git config user.name "personal-login"
$ git config user.email "your_presonal_email@example.com" 

or you can have global git config

$ git config --global user.name "work-login"
$ git config --global user.email "your_work_email@example.com"

then use normal flow to push your code

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