VS Code - Personal GitHub + GitHub Enterprise

VS Code Multi-GitHub Setup Guide

vscode github ssh windows development

Cleanly separate Personal GitHub (github.com) and GitHub Enterprise on Windows 11, using SSH keys and VS Code profiles.

---

Overview

Component	Personal	Work
VS Code Profile	Settings Sync ON (GitHub.com)	Settings Sync OFF (Enterprise)
SSH Key	id_ed25519_personal	id_ed25519_work
Git Identity	~/.gitconfig-personal	~/.gitconfig-work
Folder	C:\dev\personal	C:\dev\work

---

Prerequisites

• Windows 11
• Git for Windows installed (includes OpenSSH)
• VS Code installed
• GitHub.com account (personal) + GitHub Enterprise account

---

Create Folder Layout

mkdir C:\dev\work
mkdir C:\dev\personal

---

Create SSH Keys

ssh-keygen -t ed25519 -C "you@company.com" -f $env:USERPROFILE\.ssh\id_ed25519_work
ssh-keygen -t ed25519 -C "you@gmail.com" -f $env:USERPROFILE\.ssh\id_ed25519_personal

Upload public keys:

• id_ed25519_work.pub to Enterprise GitHub
• id_ed25519_personal.pub to GitHub.com

---

Start SSH Agent

Start-Service ssh-agent
# (Optional admin-only)
# Set-Service ssh-agent -StartupType Automatic

---

SSH Config

Edit C:\Users\<you>\.ssh\config:

Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_ed25519_personal
  IdentitiesOnly yes
 
Host github.mycompanyname.com
  HostName github.mycompanyname.com
  User git
  IdentityFile ~/.ssh/id_ed25519_work
  IdentitiesOnly yes

Test Connection

ssh -T git@github.com
ssh -T git@github.mycompanyname.com

Fix known_hosts Permission Errors

$me  = (cmd /c whoami)
$ssh = "$env:USERPROFILE\.ssh"
$kh  = "$ssh\known_hosts"
 
icacls $ssh /grant:r ("{0}:(F)" -f $me) "SYSTEM:(F)"
cmd /c takeown /F "$kh"
icacls $kh /grant:r ("{0}:(F)" -f $me) "SYSTEM:(R)"
attrib -R "$kh"

---

Git Identity Per Directory

Edit C:\Users\<you>\.gitconfig:

[user]
    name = Default User
    email = default@example.com
 
[includeIf "gitdir:C:/dev/work/"]
    path = ~/.gitconfig-work
 
[includeIf "gitdir:C:/dev/personal/"]
    path = ~/.gitconfig-personal

Create separate config files:

# ~/.gitconfig-work
[user]
    name = Work Name
    email = you@company.com
 
# ~/.gitconfig-personal
[user]
    name = Personal Name
    email = you@gmail.com

---

Clone Repos

# Work
cd C:\dev\work
git clone git@github.mycompanyname.com:Org/repo.git
 
# Personal
cd C:\dev\personal
git clone git@github.com:user/repo.git

---

VS Code Profiles

Profile	Settings Sync	Sign In To
Personal	ON	GitHub.com
Work	OFF	Enterprise

Assign profiles to workspaces in VS Code.

---

Validate

git remote -v
git config user.email

---

Troubleshooting

Issue	Solution
Unprotected key warnings	Fix key ACLs - only you + SYSTEM Read
known_hosts permission errors	Make known_hosts writable
ssh-agent auto-start denied	Run Set-Service line in admin shell only
