What is LoginSign?

LoginSign is a sign-in service that lets people log in to other apps without sharing their private email address everywhere. The idea is simple: easy sign-in like major platforms, with stronger privacy and better user control.

Who is LoginSign for?

• End users: People who want fast sign-in without creating a new password for every app and without exposing their real email address.
• Developers and product teams: Apps that want modern authentication without building a full identity and OAuth stack from scratch.
• Privacy-conscious organizations: Companies that want secure user identity with minimal data sharing.

Why was LoginSign built?

Many sign-in systems are convenient, but often share more user data than necessary. LoginSign was built to solve exactly that problem: deliver smooth authentication while making privacy a core part of the product.

In practice, this means apps only receive the information needed for authentication, and users get better transparency and control over connected apps.

What are our goals?

• Simplicity: Make sign-up and sign-in fast and understandable.
• Privacy: Protect real email addresses and sensitive profile data wherever possible.
• Security: Build on modern authentication standards and secure defaults.
• Control: Let users understand and manage which app can access which data.
• Accessible infrastructure: Offer trustworthy sign-in foundations for small and medium products, not only large platforms.
