GitHub and Developer Identity
GitHub is the world's largest code collaboration platform, owned by Microsoft. For most developers, GitHub is a professional identity platform — your public repositories, contributions, and activity form a portfolio that is often reviewed by employers, collaborators, and the open source community.
This creates a different dynamic than most platforms: for professional use, your GitHub identity should be real and persistent. For testing, automation, and secondary accounts, temporary email is appropriate.
When Temp90 Is Appropriate for GitHub
Testing and CI/CD accounts: Automated testing pipelines may require GitHub accounts with specific permission levels. Creating test accounts with Temp90 provides clean, purpose-specific accounts.
Organization testing: Testing GitHub organization features, team permissions, and access management requires multiple test user accounts.
Open source contribution anonymity: Developers who want to contribute to open source projects without connecting the contributions to their professional identity may create separate accounts for specific contribution contexts.
Bot and automation accounts: GitHub Actions and automation workflows sometimes require separate service accounts. Temp90 provides the email for these accounts.
When to Use a Real Email for GitHub
Professional portfolio accounts: Your main GitHub account should use a real, permanent email — it is your professional development identity.
Organization accounts: Business GitHub accounts tied to company billing require real contact information.
GitHub Sponsors: Receiving payments through GitHub Sponsors requires real identity verification.
Creating a GitHub Account with Temp90
Step 1: Open Temp90 and generate a temporary email (Gmail-style for best compatibility).
Step 2: Navigate to github.com/signup.
Step 3: Enter your Temp90 email, a username, and password.
Step 4: GitHub sends a verification code. Retrieve it from your Temp90 inbox.
Step 5: Complete the verification and any additional account setup steps.
Step 6: Your GitHub account is active.
GitHub Developer Settings and Privacy
For your main professional GitHub account, review privacy settings:
- Settings > Emails: Enable "Keep my email address private" to prevent your email from appearing in commit metadata
- Settings > Profile: Limit public-facing personal information
- Settings > Security: Enable 2FA (hardware key or authenticator app)
The "Keep my email address private" setting is particularly important: without it, your email address may appear in the metadata of commits you make to public repositories — visible to anyone who inspects the commit history.
GitHub Actions and Automation
For GitHub Actions workflows that interact with the GitHub API, service accounts with dedicated emails (not Temp90) are typically better — these accounts need to remain persistent and accessible for CI/CD operations. Use a dedicated service account email rather than a temporary one for production automation.
Frequently Asked Questions
Can GitHub detect that I used a temporary email?
GitHub's validation is less aggressive than some consumer platforms. Temp90's addresses generally pass GitHub's standard validation.
Will GitHub delete my account if I used a temporary email?
GitHub account policies focus on violation of terms (spamming, abuse, IP theft) rather than the email provider used at registration.
How do I prevent my email from appearing in GitHub commits?
In GitHub Settings > Emails, enable "Keep my email address private." GitHub provides a no-reply email address to use in your git configuration instead of your real email.
Conclusion
GitHub's role as a professional developer identity platform means that primary accounts should use real, permanent emails. Temp90 serves the testing, automation, and secondary account use cases where disposable email is appropriate and professional identity is not at stake. Combined with GitHub's email privacy settings, developers can manage their public commit metadata without exposing their real email address even in their primary account.
