Getting Started

LoginSign provides privacy-first social authentication. User emails are masked (e.g. x9s8d7@loginsign.com) and never exposed to your application.

Prerequisites

• A LoginSign developer account (create one at the landing page)
• A registered application in the Developer Portal
• Client ID and Client Secret from your app settings

Quick Start (5 minutes)

1. Log in and open the Developer Portal
2. Create a new app or select an existing project
3. In Settings, use Quick configuration to get pre-filled credentials and code (no manual copy-paste of Client ID)
4. Add your callback URL in Settings → Redirect URIs, then add the LoginSign script and sign-in flow to your app
5. Copy the full config block if you want to feed it to an AI for implementation

What You'll Get

After a successful sign-in, your application receives:

• User ID — A unique, stable identifier
• Display name — User-provided or from social provider
• Masked email — Forwarding address (e.g. x9s8d7@loginsign.com)

Continue to Installation for implementation details.
