📌 Why This Setup is Needed

When using multiple GitHub accounts on the same system, you may face:

• Authentication conflicts
• Wrong account commits
• Push/pull permission issues

This setup solves these problems by:

• Using separate SSH keys
• Creating SSH aliases
• Assigning identity per repository

Accounts Used

Type	Email	Username
Personal	yashbelgahe99@gmail.com	ycode99
Work	yashwant@gmail.com	yashwant

🧠 How It Works

Each GitHub account is mapped to a unique SSH key and alias:

• github-personal → Personal account
• github-work → Work account

This ensures Git uses the correct account automatically.

⚙️ Step 1: Generate SSH Keys

1.1 🔹Work Account

ssh-keygen -t ed25519 -C "yashwant@gmail.com"

Save as:

C:\Users\yashq\.ssh\id_ed25519_work

1.2 🔹Personal Account

ssh-keygen -t ed25519 -C "yashbelgahe99@gmail.com"

Save as:

C:\Users\yashq\.ssh\id_ed25519_personal

✅ Resulting Structure

C:\Users\yashq\.ssh\
├── config
├── id_ed25519_work
├── id_ed25519_work.pub
├── id_ed25519_personal
├── id_ed25519_personal.pub

🧩 Step 2: Configure SSH

Create or edit the SSH config file:

Note: The SSH config file is typically located at:

C:\Users\yashq\.ssh\config

Add the following configuration:

# Work Account
Host github-work
  HostName github.com
  User git
  IdentityFile C:\Users\yashq\.ssh\id_ed25519_work

# Personal Account
Host github-personal
  HostName github.com
  User git
  IdentityFile C:\Users\yashq\.ssh\id_ed25519_personal

🔗 Step 3: Add SSH Keys to GitHub Accounts

3.1 Add SSH Keys to Work GitHub account

Open the terminal and run:

type C:\Users\yashq\.ssh\id_ed25519_work.pub

Enter:

Copy the work Key :

Add Keys to GitHub

• Go to GitHub on browser → Settings
• Navigate to SSH and GPG Keys
• Click New SSH Key
• Paste the copied key
• Save the key

3.2 Add SSH Keys to personal GitHub account

Note: follow same steps for Add SSH Keys to personal GitHub account:

Open the terminal and run:

type C:\Users\yashq\.ssh\id_ed25519_personal.pub

Enter:

Copy the Personal Key :

Add Keys to GitHub

• Go to GitHub on browser → Settings
• Navigate to SSH and GPG Keys
• Click New SSH Key
• Paste the copied key
• Save the key

🧪 Step 4: Test SSH Connection

Note: After adding the SSH keys to both accounts, run the following commands to verify the connection.

Go to Work account: Type:

ssh -T git@github-work

Output:

Hi <username>! You've successfully authenticated.

Go to Personal account: Type:

ssh -T git@github-personal

Output

Hi <username>! You've successfully authenticated.

📥 Step 5: Clone Repositories

Format:

git clone git@<alias>:<username>/<repo>.git

Personal Repository:

git clone git@github-personal:ycode99/<repo-name>.git

Work Repository:

git clone git@github-work:yashwant/<repo-name>.git

👤 Step 6: Set Git Identity (Per Repository)

Note: Git identity is required only when creating commits. It determines which account the commit will be attributed to.

Rule:

If no commit is created, Git identity is not required.

If you are committing changes, Git identity must be configured.

Work Repository:

git config user.name "Yashwant"
git config user.email "yashwant@gmail.com"

Personal Repository:

git config user.name "ycode99"
git config user.email "yashbelgahe99@gmail.com"

⚠️ Important Rules

❌ Do NOT use:

git@github.com:...

✅ Always use:

github-work
github-personal

🔍 Quick Debug Commands

git remote -v
git config user.email
ssh -T git@github-personal

🚨 Common Mistakes

• Using default GitHub URL instead of SSH alias
• Not setting Git identity before commit
• Adding SSH key to the wrong account

🖥️ GitHub Desktop Note

GitHub Desktop:

• Uses the logged-in account
• Does not fully support SSH alias switching

👉 Recommended: Use VS Code + Terminal

📂 Recommended Folder Structure

C:\Users\yashq\work\
C:\Users\yashq\personal\

✅ Summary

This setup provides:

• Secure SSH authentication
• Correct commit attribution
• Smooth multi-account workflow
• Production-ready Git environment
