Multiple SSH Keys settings for different github account

create different public key

create different ssh key for different github accounts (must give filename while creating, else it'll overwrite - ex: ~/.ssh/id_ed25519_suryabigapp)

$ ssh-keygen -t ed25519 -C "[email protected]"
$ ssh-keygen -t ed25519 -C "[email protected]"

for example, 2 keys created at:

~/.ssh/id_ed25519_suryabigapp
~/.ssh/id_ed25519_suryatct

Modify the ssh config

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

Then add config for different accounts

#suryabigapp account
Host github.com-suryabigapp
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_ed25519_suryabigapp

#suryatct account
Host github.com-suryatct
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_ed25519_suryatct

Change repo url from HTTPS to SSH Reference and modify your Git config

cd to your project repo folder ex: bigapp-repo

git remote set-url origin [email protected]:bigappcompany/bigapp-repo.git

modify git config for bigapp-repo

$ git config user.name "suryabigapp"
$ git config user.email "[email protected]" 

cd to different project repo folder ex: curio-repo

git remote set-url origin [email protected]:curio-com/curio-repo.git

modify git config for curio-repo

$ git config user.name "suryatct"
$ git config user.email "[email protected]" 

then use normal flow to push your code

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