How It Works

  • PHP 7.4 or higher
  • G-SSO API credentials (Client ID and Client Secret)

External Services

This plugin connects to external services to provide wallet authentication functionality. All connections use HTTPS encryption.

G-SSO Authentication API

Service Provider: G-SSO Authentication Service
Service URL: https://g-sso.com
Purpose: Verifies cryptographic signatures from cryptocurrency wallets to authenticate users

Data Sent:
* Wallet address (public blockchain information)
* Cryptographic signature (for verification only)
* Timestamp (to prevent replay attacks)
* Chain ID (blockchain network identifier)

When Data is Sent:
Only when a user clicks “Connect Wallet” and signs the authentication message in their wallet.

Privacy Policy: https://g-sso.com/privacy
Terms of Service: https://g-sso.com/terms

Legal Basis:
G-SSO is operated by Go2Glory LLC. Wallet addresses are public blockchain data and do not constitute personal information under GDPR. No personally identifiable information (PII) is collected without explicit user consent.

QR Code Generation Service

Service Provider: goQR.me / QRServer.com
Service URL: https://api.qrserver.com
Documentation: https://goqr.me/api/
Purpose: Generates QR codes for mobile wallet authentication

Data Sent:
* Temporary authentication URL (session link with no personal data)
* QR code styling parameters (size: 160×160 pixels, color: #667eea)

When Data is Sent:
Only when the wallet connection modal is displayed and user is on a mobile device. QR codes are generated on-demand for that session only.

Privacy Policy: https://goqr.me/privacy-safety-security
Terms of Service: https://goqr.me/legal/tos-api.html

Data Protection:
QR codes contain only temporary session URLs that expire after use. No personal or sensitive information is transmitted. The session URL is a one-time-use token that becomes invalid after authentication completes.

Data Protection Summary

  • HTTPS Encryption: All external connections use SSL/TLS encryption
  • Public Data Only: Wallet addresses are public blockchain information
  • No PII Collection: No names, emails, or personal data required
  • Temporary Sessions: Authentication URLs expire after single use
  • GDPR Compliant: Minimal data collection by design
  • User Control: Users control wallet access via their wallet application

Do users need cryptocurrency to use this?

No. Users only need a cryptocurrency wallet installed (like MetaMask browser extension). They don’t need to own any cryptocurrency to authenticate.

What wallets are supported?

  • MetaMask (Desktop & Mobile)
  • Coinbase Wallet
  • Rainbow Wallet
  • Trust Wallet
  • And any wallet that supports signing messages

Is this secure?

Yes. The plugin uses cryptographic signature verification, which is the same technology used for cryptocurrency transactions. Users never share their private keys.

What happens if a user loses access to their wallet?

Users can still use traditional WordPress password reset. We recommend users set up an email address in their profile for account recovery.

Does this work with WooCommerce?

Yes. Add the [gsso_login] shortcode to your WooCommerce “My Account” page or any checkout page to enable wallet login for customers.

Can I customize the button appearance?

Yes. Go to Settings G-SSO Wallet Login to customize button text, position, and display options.

Where do I get API credentials?

Visit https://g-sso.com to create a free account and obtain your Client ID and Client Secret.

Is this GDPR compliant?

Yes. Wallet addresses are public blockchain data and do not constitute personal information under GDPR. The plugin collects minimal data by design.

What if I don’t have a wallet?

Creating a wallet takes 2 minutes at MetaMask.io (free). Or you can continue using traditional email/password login.

Can I use this on multiple pages?

Yes. Add the [gsso_login] shortcode to any page, post, or custom post type.
