Why Site Kit Should Allow Username Selection Instead of Email for Google Sign-In: Currently, Site Kit by Google uses email addresses as default identifiers for Google Sign-In, which can expose users to privacy and security risks such as phishing, email scraping, and identity exposure. A more secure alternative would be to allow users to create unique usernames instead of displaying their email addresses.
This approach enhances user privacy, reduces the risk of targeted attacks, and offers better control over personal identity. Implementing username support within Site Kit would require some updates to the sign-in flow but would significantly boost security, user trust, and the overall user experience.
Site Kit by Google is one of the most powerful tools available for WordPress users who want seamless integration with Google’s services like Search Console, Analytics, AdSense, and more. While the plugin excels in functionality, one critical area that could be improved is user sign-in security.
Currently, Site Kit uses email addresses as default identifiers when users sign in with Google. While this is convenient, it poses significant security and privacy risks. A more secure and privacy-conscious approach would be to allow users to select unique usernames instead of exposing their email addresses.
The Problem: Email-Based Sign-In Creates Security Risks
While the current Google Sign-In method is easy and fast, it can unintentionally compromise user data. Here’s how:
✅ Email Exposure: Anyone who interacts with the system can potentially discover user email addresses.
✅ Phishing Risk: Known or predictable emails make phishing easier for malicious actors.
✅ Scraping Vulnerability: Bots can scrape public-facing elements and harvest emails for spam or social engineering.
The Solution: Let Users Choose Unique Usernames
Replacing email addresses with user-selected usernames as the primary identifier offers numerous advantages in terms of security, privacy, and user experience.
| Feature/Concern | Current State in Site Kit | Recommended Update | Benefit |
|---|---|---|---|
| Sign-In Identifier | Google Email Address | User-defined Unique Username | Hides personal email, improves privacy |
| Security Risk | Email addresses exposed | Reduced exposure through username use | Minimizes phishing and brute-force attack vectors |
| Email Scraping Risk | High | Low | Reduces automated email harvesting |
| User Identity Customization | Not supported | Supported | Users can manage how they are identified |
| Account Management | Tied to Google email | Username + optional Google sign-in | Offers more control and flexibility |
| Username Uniqueness | Not applicable | Required (check availability at signup) | Ensures each identity is distinct |
| Password Option | Not applicable (Google only) | Optional for non-Google sign-in | Adds flexibility for users preferring traditional login |
| Ease of Integration | Simple Google Sign-In | Requires custom username logic + Google fallback | Slightly more complex, but more secure |
| User Trust | Moderate (email visible) | High (private and secure login) | Builds confidence in platform security |
| Implementation Difficulty | None | Moderate | Worth the effort for long-term security |
Benefits of Username-Based Sign-In for Site Kit
1. Enhanced Security
Switching to usernames reduces the chance of targeted attacks by obscuring real email addresses from prying eyes.
2. Better Privacy
Users can keep their email addresses private, avoiding the risk of them being linked to other services or scraped.
3. Reduced Spam & Phishing
Using usernames drastically lowers the chances of email scraping or phishing emails targeting Site Kit users.
4. Flexible Identity Management
Users get more control over their account—from selecting a username to changing it as needed.
5. Future-Proof User Experience
The world is moving toward privacy-first systems. Giving users the option to hide sensitive information is the way forward.
How Site Kit Could Implement Username Support
Implementing username functionality is entirely achievable with some smart design and integration choices:
Username Selection at First Sign-In
When users first log in with Google, prompt them to choose a unique username (check for availability in real time).
Hybrid Sign-In System
Support both:
- Google Sign-In (with username fallback)
- Traditional username/password for advanced users
Secure Password Handling
If password support is introduced, use modern encryption standards (e.g., bcrypt with salting) to securely store credentials.
Account Settings for Username Management
Let users change their username anytime from the account dashboard (subject to availability and verification).
Final Thoughts
Enabling username selection instead of exposing email addresses by default is a simple yet powerful upgrade for Site Kit’s authentication system. Not only does it address modern security and privacy expectations, but it also improves trust and user satisfaction.
Frequently Asked Questions (FAQs)
1. Why does Site Kit use email addresses for Google Sign-In?
Site Kit by Google uses the email address linked to your Google account as the default identifier for sign-in, simplifying authentication and account linking. However, this practice can expose users to privacy and security risks.
2. What are the risks of using email addresses for login identification?
Using email addresses as usernames can expose users to phishing, brute-force attacks, spam, identity tracking, and scraping by bots or malicious users, especially if the emails are visible or guessable.
3. How would using a username instead of an email help improve security?
Usernames add a layer of abstraction between your identity and your credentials. They are harder to guess, aren’t linked to your personal inbox, and help keep your email address private—reducing phishing and hacking risks.
4. Can usernames be used with Google Sign-In?
While Site Kit currently doesn’t support it, usernames can technically be integrated alongside Google Sign-In. The platform would need to allow users to create a unique username during the initial sign-in process.
5. Will allowing usernames replace Google Sign-In completely?
Not necessarily. A well-designed system can support both options—allowing users to continue using Google Sign-In while also selecting a username to use within the platform for identity and security purposes.
6. Is it harder for users to remember usernames compared to emails?
Not really. Many users prefer custom usernames they can personalize, especially if they use the same one across multiple platforms. Plus, usernames can be simpler and more memorable than long email addresses.
7. Will adding username support make Site Kit harder to use?
No. If implemented correctly, users would only need to select a username once, during their first sign-in. From there on, they can use either method seamlessly without added complexity.
8. What happens if two users choose the same username?
The system should automatically check for username availability and prompt users to choose an alternative if the one they want is already taken—just like most modern platforms do.
9. Can a user change their username later?
Ideally, yes. Site Kit could implement a user settings option that allows changing usernames, with some limitations to prevent abuse or confusion.
10. Would usernames be publicly visible?
That depends on the platform’s design. However, even if usernames are visible, they are generally safer than exposing personal email addresses to the public or other users.
11. How does username-based login reduce email scraping?
Bots and malicious actors often scrape public pages or platform metadata looking for email addresses. Replacing email-based logins with usernames significantly reduces this attack vector.
12. Is this username system similar to what other platforms use?
Yes. Platforms like Twitter, GitHub, Reddit, and Discord all use usernames instead of emails for public identity, keeping emails private and protected in the background.
13. Will this affect existing Site Kit users?
If implemented correctly, existing users could be prompted to choose a username upon their next login—without disrupting current access or requiring password resets.
14. Will passwords be required if usernames are introduced?
Only if Site Kit chooses to support traditional logins. Google Sign-In can still be used in tandem with usernames, and password-based access can be optional for users who prefer it.
15. How does this change benefit WordPress site owners using Site Kit?
It gives WordPress site owners better control over their login identity, improves security on shared or multi-user environments, and aligns with best practices for privacy-first website management.
16. How difficult is it to implement username support in Site Kit?
It would require moderate development effort—modifying the sign-in flow, adding username fields, and managing username uniqueness. However, the security and UX benefits outweigh the complexity.
17. Can usernames help reduce account-related social engineering attacks?
Yes. If a hacker doesn’t know your email, they’ll have a harder time impersonating or contacting you through phishing attempts, making social engineering attacks more difficult to execute.
18. What is the difference between login identity and display identity?
Login identity (e.g., username or email) is used for authentication, while display identity is how you appear publicly. Usernames can serve both purposes while keeping email addresses hidden.
19. Is Site Kit by Google expected to introduce this feature?
There is no official announcement yet, but the suggestion aligns with modern web security practices and could be considered in future updates if user demand and privacy trends push in that direction.
20. How can I suggest this feature to the Site Kit team?
You can submit feedback directly through the WordPress plugin support forum or through Google’s Site Kit GitHub repository under “Issues” or “Feature Requests.”
As digital privacy and security continue to grow in importance, it’s crucial for tools like Site Kit by Google to adapt. Relying on email addresses for Google Sign-In may offer convenience, but it comes at the cost of exposing users to unnecessary risks like phishing, scraping, and identity leaks. By allowing users to choose a unique username instead, Site Kit can enhance its overall security framework, offer better privacy protection, and provide users with more control over their online identity.
While implementing this feature may require some adjustments, the long-term benefits in trust, safety, and user experience make it a smart and forward-thinking move. It’s time Site Kit evolved to meet modern security expectations—starting with the simple yet powerful option of username-based sign-in.
