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

Navigate to your GitHub email settings to find your noreply address:

1. Go to [github.com/settings/emails](https://github.com/settings/emails)
2. Locate the "Keep my email addresses private" section
3. Your noreply address appears below this option in the format:

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

Example: [email protected]

Copy this complete address including the numeric ID prefix - you'll need it for configuring Git.

The numeric ID uniquely identifies your account, allowing GitHub to properly attribute commits made with the noreply address to your profile.

Configure Git to use your GitHub noreply email for all commits:

Global configuration (applies to all repositories):

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

Repository-specific configuration:

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

Verify the configuration:

git config user.email

This should output your noreply email address. Replace the placeholder with your actual noreply address from Step 1.

New commits will now use the noreply address automatically.

If only your latest commit contains the private email, amend it to update the author information:

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

Explanation:
- --amend: Modifies the most recent commit
- --reset-author: Updates the author email to your current Git configuration
- --no-edit: Preserves the existing commit message

Attempt the push again:

git push

If the push succeeds, you're done. If multiple commits contain your private email, proceed to the next step.

When several commits contain your private email, you need to rewrite their history.

Identify affected commits:

git log --format='%h %ae %s' | head -20

For a small number of recent commits (soft reset):

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

# Create new commit(s) with the correct email
git commit -m "Your commit message"

For more commits (interactive rebase):

# Start interactive rebase for the last N commits
git rebase -i HEAD~5

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

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

# Repeat until complete

Note: Rewriting commits changes their SHA hashes, which affects collaboration if commits were already pushed.

Push your fixed commits to GitHub:

git push

If the commits were already on the remote and you rewrote them, you'll need to force push:

git push --force-with-lease

Using --force-with-lease instead of --force adds a safety check that prevents overwriting work pushed by others since your last fetch.

Caution: Only force push to branches where you're the sole contributor, or coordinate with your team first. Never force push shared branches like main without explicit agreement.

If you prefer using your real email in commits and understand the privacy implications:

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

Privacy considerations:
- Your email will be visible in commit history to anyone viewing the repository
- Public repositories expose emails to scrapers and bots
- Developer-targeted phishing and spam is prevalent
- Email exposure in commits cannot be undone after pushing

Recommendation: Using the noreply email provides privacy protection while maintaining full commit attribution to your GitHub profile.
