Background

The replacement cycle for mobile phones is approximately 30 months.

Toss users are required to reinstall the app every 30 months due to device changes.

After reinstalling the app, more than 30% of attempted logins result in user dropout during the login process.

Simplifying the login process after app reinstallation can reduce dropouts and consequently increase the Monthly Active Users (MAU) of the Toss app.

Planning

In the registration process, there was three essential steps: CI (Customer Identification) verification, device possession authentication, and PIN password verification.

Device possession authentication is necessary for real-time device security and cannot be omitted.

The PIN password is a minimum security requirement and cannot be skipped.

To verify CI, Toss application require user information input and identity verification through a verification agency.

Growth modeling stats

Problem

Toss already has 30 million registered users. This means that most of Korea's 40 million mobile users are using it.

However, Toss' Carring-Capacity has been stagnant for three years.

Are there a lot of users leaving? When I looked into it, it wasn't that big. So, is retention low? Due to the nature of the financial app, the retention rate was 50%, and on a MoM (Month of Month) basis, it was 85%, meaning users were using it very actively.
