Eliminates the need to remember and manage multiple IDs and passwords across websites by providing a unified phone-number-based login mechanism with enhanced security through distributed credential storage (USIM, App, Server)

1. User installs extension from Chrome Web Store 2. User visits a partner website with a login form 3. Extension content script detects login fields (ID and password inputs) via keyword matching 4. Extension injects clickable overlay icon near the login fields 5. User clicks the icon → iframe from sepay.org opens in a popup 6. User enters phone number and authenticates (first time: sets initial password) 7. Extension auto-fills the site's ID/password fields via postMessage communication 8. Subsequent visits: user only needs to enter their sepay password to auto-login

Target users: Korean internet users who want simplified login across multiple websites / Users concerned about password security and phishing attacks / Users of partner Korean e-commerce and service websites

The main logic file sepay_extension.min.js is minified, making detailed code analysis harder
The iframe content loaded from sepay.org (sepay_view_ex.html) cannot be inspected—login/payment details are hidden in the remote service
The channel list is fetched dynamically from resource.hectoinnovation.co.kr, so the full list of supported partner sites is unknown

Monetization

No paid features detected

No payment-related keywords (premium, subscribe, payment, price, billing, stripe, etc.) found anywhere in the extension source code. The store description mentions '안심보험 최대 100만원 지원' (safety insurance up to 1M KRW via Meritz Fire Insurance) as a bundled benefit, not a paid feature. The extension's code contains no gating logic, no payment API calls, and no upgrade prompts. The insurance coverage appears to be included as a free service benefit.

Confidence: 80
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension's core workflow requires the user to authenticate with the sepay.org service. When clicking the injected login helper icon, an iframe from https://sepay.org/html/sepay_view_ex.html is opened (line 429 of sepay_extension.min.js). Per the store description, the user must enter a phone number and set an initial password ('휴대폰번호 입력 후 초기 비밀번호 설정'). The extension itself has no background script or popup—its only interactive flow depends on the sepay.org authentication service. After initial setup, subsequent logins require entering a stored password.
