How to Change Your GitHub Account on macOS

A complete step-by-step guide to switch GitHub accounts on your Mac

11. Remove Current GitHub Credentials

First, check which credential helper you're currently using:

git config --global credential.helper

Remove stored credentials from macOS Keychain (press Enter twice after the last line):

git credential-osxkeychain erase
host=github.com
protocol=https

💡 Manual Method: Open Keychain Access app (Cmd + Space, search "Keychain Access"), search for "github.com", and delete all GitHub-related entries.

22. Update Git Configuration

Check your current Git username and email:

git config --global user.name && git config --global user.email

Update to your new GitHub username:

git config --global user.name "Your New Name"

Update to your new GitHub email:

git config --global user.email "newemail@example.com"

Verify your changes were applied correctly:

git config --global --list

33. Logout from Current GitHub Account

Logout from your current GitHub account:

gh auth logout
