Managing multiple GitHub account using git in windows

Wanna use another GitHub account in my windows pc but wait I already got my personal account added in git.
No problem here you can see how you can manage multiple accounts without any hassle:

Note: This DIY is meant for windows users.

Set up SSH Keys

So let's consider your two GitHub accounts are named githubPersonal and githubWork, respectively.

Create two SSH keys, saving each to a separate file:
Execute the below mentioned commands in gitbash

$ cd ~/.ssh

$ ssh-keygen -t rsa -C "your_email_id_associated_with_githubPersonal_account

save it as id_rsa_personal when prompted (you can rename personal)
$ Enter passphrase (empty for no passphrase): skip this by pressing enter
$ Enter same passphrase again: skip this by pressing enter

$ ssh-keygen -t rsa -C "your_email_id_associated_with_githubWork_account"

save it as id_rsa_work when prompted (you can rename personal)
$ Enter passphrase (empty for no passphrase): skip this by pressing enter
$ Enter same passphrase again: skip this by pressing enter

The above commands setup the following files:
id_rsa_personal
id_rsa_personal.pub
id_rsa_work
id_rsa_work.pub

Add the keys to your Github accounts:

Copy the key to your clipboard by opening the file in vs code:

$ code . id_rsa_personal.pub

Add the key to your account:
Go to your GitHub Account Settings
Click “SSH Keys” then “Add SSH key”
Paste your key into the “Key” field and add a relevant title
Click “Add key” then enter your GitHub password to confirm.

Repeat the process for your githubWork account.

Create a configuration file

Create a configuration file to manage the separate keys in ~/.ssh/ using
$ touch config

Edit the file using the text editor of your choice. I used vs code -
$ code . config

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

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

Update stored identities

initialize the ssh-agent (use powershell)

Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Clear currently stored identities:
$ ssh-add -D
Add new keys:

$ ssh-add id_rsa_personal

$ ssh-add id_rsa_work

Test to make sure new keys are stored:

$ ssh-add -l

Test to make sure Github recognizes the keys:

$ ssh -T personal

Hi githubPersonal! You've successfully authenticated, but GitHub does not provide shell access.

$ ssh -T work

Hi githubWork! You've successfully authenticated, but GitHub does not provide shell access.

Test PUSH

On Github, create a new repo in your personal account, githubPersonal, called test-personal.
Back on your local machine, create a test directory:
$ cd ~/documents
$ mkdir test-personal
$ cd test-personal
Add a blank “readme.md” file and PUSH to Github:
$ touch readme.md
$ git init
$ git add .
$ git commit -am "first commit"
$ git remote add origin git@personal:githubPersonal/test-personal.git
$ git push origin master
Notice how we’re using the custom account, git@personal, instead of git@github.com.

Repeat the process for your githubWork account.
