Problem

Why Do We Need Login 3.0 Now?

As stricter cookie regulations limit marketing strategies, companies face an urgent need to improve the quality of first-party data and integrate IDs to maximize group synergies.

However, traditional ID integration had an inefficient structure in which separate IDs were issued for each service, posing the challenge of requiring a tremendous amount of time and cost for system integration. Login 3.0 solves both of these challenges at once.

Our Solution

Three Core Solutions

Login 3.0 Features
single sign-on
Feature 01

Single Sign-On Experience

Seamlessly access multiple services with a single login. This reduces the burden of password management while improving security and user satisfaction.

Data Collection in Compliance with Laws and Regulations
Feature 02

Data Collection in Compliance with Laws and Regulations

Users manage their consent in a self-sovereign manner. You can legally collect first-party data while complying with the GDPR and the Personal Information Protection Act.

Integration of Existing Systems
Feature 03

Flexible Integration with Existing Systems

Connect to your existing infrastructure using an OIDC-protocol-compatible SDK. You can implement it without major system overhauls, allowing you to maximize the value of your existing investments.

3 Points

Why Choose Login 3.0?

We differentiate ourselves from other ID platforms based on three key factors: cost, technology, and future potential.

Reducing Adjustment Costs

Since information retrieval requirements can be customized for each service, there is no need to standardize information retrieval across all services, which significantly reduces development costs.

No major renovations required

The SDK tools simplify implementation. They can be deployed without requiring major changes to existing systems, minimizing the need for engineering resources.

Future scalability

Built on Web 3.0 technology. It can be easily adapted to changing trends, and DID/VC enables users to exercise sovereign control over their own identities.

Implementation

Implementation Flow

We provide step-by-step support, from requirements gathering through proof of concept (PoC) to the production release.

01

Requirements Gathering

We will conduct interviews to understand the existing system configuration, ID requirements, and regulatory requirements, and formulate the optimal implementation strategy.

02

SDK Integration

Integrate an OIDC-compliant SDK into your existing system. Achieve integration without the need for major system overhauls.

03

Conducting a Proof of Concept

Pilot test in a real-world environment. Verification of the authentication flow, data collection, and consent management.

04

Production Release

Migration to a scalable production environment. Long-term operation is supported through ongoing support.

Frequently Asked Questions

What does “personal IDs will be standardized” mean?

+

With the previous system, different IDs were issued for each service, making it impossible to analyze users across services. With Login 3.0, each user maintains the same ID across all services, enabling cross-service analysis of customer data and the implementation of marketing initiatives.

Is personal information ever made public on the blockchain?

+

No. Web 3.0 technology is used solely to generate users’ DIDs (Decentralized Identifiers). Personal information is never recorded or disclosed on the blockchain; actual personal information is securely stored in the user’s wallet.

Will major modifications to the existing system be necessary?

+

In most cases, this is not necessary. Since we provide an OIDC-protocol-compliant SDK, integration can be completed within a few weeks for standard web applications. You can also migrate in phases while leveraging your existing authentication infrastructure.
