Managing Multiple SSH Keys in Git on Windows

1. Create the first SSH key by running the following command:

   ssh-keygen -t rsa -C "someone@example.com" -f "/c/Users/username_for_pc/.ssh/first_username"
   

2. Next, create the second SSH key by executing the command:

   ssh-keygen -t rsa -C "someone2@example.com" -f "/c/Users/username_for_pc/.ssh/second_username"
   

3. Now, we need to create a config file without any extension. You can either use VS Code or download the config file and modify it. Here’s the content of the config file:

# GitLab configuration
Host git.chalmers.se
  HostName git.chalmers.se
  User git
  IdentityFile C:\Users\username_for_pc\.ssh\first_username

# GitHub configuration
Host github.com #if both of them are github then you can change the first one to github-second
  HostName github.com
  User git
  IdentityFile C:\Users\username_for_pc\.ssh\second_username

1. Additionally, we need to edit the .gitconfig file, located at “C:\Users\username_for_pc.gitconfig,” if you have two different Git providers (e.g., GitLab and GitHub). Modify the file as follows:

[credential "https://git.chalmers.se"]
	provider = generic
[user]
	name = first_username
	email = someone@example.com

[credential "https://github.com"]
	provider = generic
[user]
	name = second_username
	email = someone2@example.com

That’s it! You have successfully configured multiple SSH keys for Git. I hope you find this information helpful.
