Summarize this article with:
Your GitHub username follows you everywhere: profile URLs, repository links, commit history, and collaborator mentions.
When that handle no longer fits your brand or career, knowing how to change GitHub username becomes necessary.
The good news? GitHub lets you update your account identifier in under 2 minutes.
The catch? Broken links, redirect quirks, and post-change cleanup tasks you need to plan for.
This guide walks you through each step of the username change process, from accessing account settings to updating local repositories and external references.
You will learn exactly what changes automatically, what breaks, and how to fix it.
How to Change The GitHub Username
Changing your GitHub username is the process of updating your account identifier through the platform’s settings panel.
This modification affects your profile URL, repository links, and how collaborators find you across the platform.
Users typically need this when rebranding their developer identity, fixing typos in their original handle, or aligning their GitHub profile with other professional accounts.
The entire username change process takes about 2 minutes and requires only basic navigation through your account settings.
Understanding what GitHub is and how it handles identity helps you anticipate the ripple effects of this change.
Prerequisites
Before you begin, make sure you have:
- Active GitHub account with verified email address
- Desktop browser access (mobile not recommended for this process)
- Your new username decided in advance
- Password ready for confirmation
Username Requirements
GitHub enforces specific username restrictions you should know.
Allowed: 1-39 characters, alphanumeric characters, and single hyphens.
Not allowed: consecutive hyphens, starting or ending with hyphens, special characters, spaces.
Time Estimate
The actual change takes under 2 minutes.
Post-change cleanup (updating local repos, notifying collaborators) varies based on your project count.
Step One: How Do You Access GitHub Account Settings?
Navigate to your account settings by clicking your profile photo in the upper-right corner of any GitHub page, then selecting “Settings” from the dropdown menu.
The settings page opens with your profile options visible in the left sidebar.
Action
- Location: Profile photo (upper-right corner) > Settings
- Navigation: Left sidebar > Account
- Result: Account settings page displays your current username
Purpose
The Account section houses all identity-related controls including username, email association, and account deletion options.
This is separate from your public profile settings where you edit your bio and display name.
Step Two: Where Do You Find the Change Username Option?
Scroll to the “Change username” section on the Account settings page and click the “Change username” button.
A warning dialog appears immediately, outlining the impact of this modification.
Action
- Location: Account settings > Change username section
- Click: “Change username” button
- Result: Warning dialog opens with impact details
Purpose
GitHub separates this option from quick-access settings because username changes have platform-wide consequences.
The confirmation dialog exists to prevent accidental modifications that could break source control workflows.
Step Three: How Do You Review Username Change Warnings?
Read the warning dialog carefully before proceeding.
GitHub lists specific impacts: broken links to your profile, repository redirect behavior, and potential issues with packages in your account namespace.
Action
- Review: Warnings about profile URL changes (returns 404 error)
- Understand: Repository redirects work automatically
- Note: GitHub Pages, gist URLs, and CODEOWNERS files need manual updates
What Changes Automatically
Repository URLs redirect from old username to new username.
Commits linked to your GitHub email stay attributed to your contribution graph.
What Breaks
Direct profile links return 404.
GitHub Mobile may show your old username until you log out and back in.
External references on LinkedIn, Twitter, or your portfolio need manual updates.
Local Git repositories with your old username in the remote URL stop pushing and pulling until updated.
Purpose
This review step prevents surprises after the change completes.
Knowing what breaks helps you prepare a cleanup checklist before clicking confirm.
Step Four: How Do You Confirm and Apply the New Username?
Click “I understand, let’s change my username” to proceed past the warning dialog.
Enter your desired new username in the text field; GitHub checks availability instantly with a green checkmark or red X.
Action
- Confirm: Click “I understand, let’s change my username”
- Enter: Type new username in the provided field
- Verify: Check the availability indicator (green = available)
- Complete: Click “Change my username”
Purpose
The username availability check prevents conflicts with existing accounts.
Once confirmed, the change applies immediately and your old username becomes available for anyone to claim.
Verification
Confirm the change worked by checking these items:
- Visit github.com/new-username to verify your profile loads
- Check that repositories appear under the new URL
- Test an old repository link to confirm redirect works
- Log out and back into GitHub Mobile to refresh the display
Your contribution graph and commit history remain intact if commits are linked to a verified email on your account.
Troubleshooting
Desired Username Is Unavailable
Try variations: add numbers, use hyphens, or check alternative spellings.
GitHub Support cannot release usernames unless you hold a trademark.
Repository Clone and Push Stops Working
Update the remote URL in each local clone:
- Run:
git remote set-url origin https://github.com/new-username/repo-name.git - Verify:
git remote -v
Understanding what Git remote is helps you manage multiple repository connections.
GitHub Pages Site Breaks
Rename your repository from old-username.github.io to new-username.github.io.
Repository Settings > General > Repository name field.
External Links Return 404 Errors
Update profile links on LinkedIn, Twitter, portfolio sites, and documentation manually.
The profile URL github.com/old-username does not redirect.
Commits Show Wrong Author
Commits stay attributed if they use an email linked to your GitHub account.
Update your local Git config if you need to change the commit email going forward.
After Changing Your Username
How Do You Update Local Git Repositories?
Each cloned repository stores the old username in its remote URL configuration.
Use git remote set-url origin with the new path, or delete and clone the repository fresh.
How Do You Protect Your Old Username?
Create a temporary GitHub account using your old username immediately after the change.
This prevents impersonation or username squatting by others; delete it after 1-2 months per GitHub’s policy.
How Do You Update External References?
Check and update these locations:
- CI/CD pipelines: GitHub Actions workflows, Jenkins, CircleCI configs
- Package registries: npm, PyPI, Docker Hub references
- Documentation: README files, wikis, external docs
- Social profiles: LinkedIn, Twitter, personal website
- Collaborator notifications: Email team members about the change
Developers working in DevOps environments should also check continuous integration and continuous deployment configurations.
