📱 Mobile App Integration Track

The fastest path to integrating logi in iOS, Android, Flutter, and React Native native apps.

Is this the right track?

• ✅ Yes: a native app users install from an app store
• ❌ Web → 🌐 Web Integration Track
• ❌ Machine-to-machine / CLI → 🔧 API · CLI Track

The four core promises

1. Public client + PKCE are required. Never hardcode client_secret into a mobile app.
2. Use a single custom-scheme redirect_uri — for example, com.example.app://oauth/1pass/callback.
3. App-to-app first, in-app browser fallback — works even when the user arrives from an in-app browser like KakaoTalk or Naver.
4. Keep the app RP and the web RP separate — don't mix mobile and web redirects under the same client_id. Details: Common / Public Clients · One RP per surface

Step 1 · Register the app

Register one RP with client_type: public. You can do this from the console or the API.

• App registration guide — console UI walkthrough
• Public Clients (PKCE-only) — API registration + redirect_uri policy
• Choosing Public vs Confidential — which one to pick

Step 2 · Platform quickstart

iOS — LogiAuth Swift Package (recommended)

On iOS, the official Swift SDK LogiAuth handles PKCE, ASWebAuthenticationSession, the in-app escape, and keychain storage for you. Reach for the SDK before you roll your own.

// Package.swift
.package(url: "https://github.com/dcode-co/logi-auth-swift.git", from: "0.2.0"),

// App.swift
import LogiAuth

@main
struct MyApp: App {
  init() {
    LogiAuth.configure(LogiAuthConfig(
      clientId: "logi_xxx",
      redirectURI: URL(string: "myapp://oauth/1pass/callback")!
    ))
  }

  var body: some Scene {
    WindowGroup {
      ContentView()
        .onOpenURL { url in _ = LogiAuth.handle(url) }
    }
  }
}

// anywhere
let result = try await LogiAuth.signIn()

Don't forget .onOpenURL { url in _ = LogiAuth.handle(url) } — the SDK receives the login callback there and completes the token exchange.

Other platforms

Follow the single page for your stack. The rest are mirrors of the same pattern.

Stack	Guide	SDK / library
iOS (Swift)	integrations/swift	LogiAuth 0.1.2 (recommended) · or roll your own ASWebAuthenticationSession + CryptoKit
Android (Kotlin)	integrations/android	LogiAuth Kotlin SDK (recommended) · or hand-rolled Custom Tabs + DataStore + Keystore
Flutter	integrations/flutter	flutter_web_auth_2 + flutter_secure_storage
React Native	integrations/react-native	react-native-app-auth + react-native-keychain

Storing credentials separately on Android

The Android (Kotlin) — Canonical/Merge page covers canonical_sub / linked_subs handling and the pattern for storing credentials separately. For a new integration, read it after you finish the Step 2 guide.

Step 3 · Avoid the mobile-specific pitfalls

• Universal Links integration guide — registering iOS Universal Links and Android App Links
• Escaping the in-app browser — when OAuth is blocked inside the KakaoTalk, Naver, or Facebook in-app browser
• Refresh token rotation policy — rotation-interval differences between Apple Sign In and Google
• First-login completion form — pattern for collecting your own extra info (role/org) once

Step 4 · Pre-build checks

• RP integration testing — verification steps for both the simulator and a real device
• Demo page walkthrough — compare against the reference implementation code
• demo.1pass.dev/oauth — mobile PKCE end-to-end walking sample (scenario deep-links)
• demo.1pass.dev/ios — iOS native (after install) — Universal Link first-try + Swift SDK
• demo.1pass.dev/app-clip — iOS App Clip (before install) — card login via QR scan
• demo.1pass.dev/android — Android native — Intent setPackage first-try + Custom Tabs fallback
• Self-diagnosis — /diagnose — check registration, redirect_uri, and scopes

Common reference (track-agnostic)

• Authorization Code Flow · PKCE · Scope reference
• Error codes · Response headers
• Security best practices (RP side)
• Login button components

Hand the whole thing to an AI

Paste @/llms-full.txt into Claude Code, Cursor, or Codex, then say:

"Integrate logi 1pass as an RP into my [iOS Swift / Flutter / Android Kotlin / RN] app, using a public client + PKCE."

→ It generates the quickstart, env, redirect_uri registration, and callback handler automatically.
