How to fix remote: error: GH007: Your push would publish a private email address in Git

First, you need to locate your GitHub-provided noreply email address:

1. Go to [github.com/settings/emails](https://github.com/settings/emails)
2. Look for the "Keep my email addresses private" checkbox
3. Below it, you'll see text containing your noreply address in this format:

{ID}+{username}@users.noreply.github.com

For example: [email protected]

Copy this address - you'll need it for the next steps.

Note: The numeric ID is unique to your account and helps GitHub link commits to your profile even when using the noreply address.

Update your Git configuration to use the noreply email for all future commits:

For all repositories (recommended):

git config --global user.email "{ID}+{username}@users.noreply.github.com"

For the current repository only:

git config user.email "{ID}+{username}@users.noreply.github.com"

Verify the configuration:

git config user.email
# Should output: {ID}+{username}@users.noreply.github.com

Replace {ID}+{username} with your actual noreply address from the previous step.

If your most recent commit contains your private email, amend it to use the new configuration:

git commit --amend --reset-author --no-edit

This command:
- --amend: Modifies the last commit instead of creating a new one
- --reset-author: Updates the author info to match your current Git config
- --no-edit: Keeps the same commit message

Try pushing again:

git push

If successful, you're done! If you have multiple commits with the private email, continue to the next step.

If several commits contain your private email, you'll need to rewrite them. First, find how many commits have the issue:

git log --oneline | head -10

For a few recent commits (soft reset approach):

# Reset to before the problematic commits (keeping changes)
git reset --soft HEAD~3  # Adjust number as needed

# Re-commit all changes with correct email
git commit -m "Your commit message"

For many commits (rebase approach):

# Start interactive rebase (adjust number of commits)
git rebase -i HEAD~5

# In the editor, change 'pick' to 'edit' for commits needing email fix
# Save and close the editor

# For each commit that pauses:
git commit --amend --reset-author --no-edit
git rebase --continue

# Repeat until rebase completes

Warning: Rewriting history changes commit hashes. If you've already pushed these commits, you'll need to force push (see Advanced Notes).

After fixing the commits, push to GitHub:

git push

If you rewrote commits that were already pushed, you'll need to force push:

# Force push (use with caution!)
git push --force-with-lease

The --force-with-lease flag is safer than --force because it will fail if someone else has pushed to the branch since your last fetch.

Important: Only force push to branches you own. Never force push to shared branches like main without team coordination.

If you intentionally want to use your real email in commits and accept the privacy implications:

1. Go to [github.com/settings/emails](https://github.com/settings/emails)
2. Find "Block command line pushes that expose my email"
3. Uncheck this option

This allows pushes with your real email but removes GitHub's privacy protection.

Consider these implications:
- Your email becomes publicly visible in commit history
- Email harvesting bots may scrape your address
- You cannot retroactively hide the email from pushed commits
- Spam and phishing targeting developers is common

Recommendation: Keep the blocking enabled and use the noreply address instead.
