+# imToken in-app browser opens but does not log in — Quick Fix
+
+## Bug
+
+imToken can be opened from Chrome into its in-app browser, but the site does not complete wallet login.
+
+## Root Cause
+
+`AutoInjectedLogin` only started when the URL contained `?autoLogin=imToken`. imToken's deeplink/in-app-browser navigation can open the page while dropping or not preserving that query string, so the auto-login effect never ran even though the page was inside imToken and an injected provider was available.
+
+## Fix
+
+Added an imToken browser fallback: if no explicit `autoLogin` query parameter exists, but the current user agent is imToken, `AutoInjectedLogin` treats it as an imToken direct-login session and runs the same injected login path.
+
+### Files Modified
+
+- `src/wallet/AutoInjectedLogin.tsx` — starts imToken direct login based on imToken in-app-browser detection when the deeplink query is missing.
+- `src/wallet/injected.ts` — exports `isImTokenBrowser()` so the auto-login flow can reuse the imToken browser detection.
+
+## Verification
+
+- `npx tsc --noEmit`
+- `npm run format:check`
+- `npm test`
+
+## Notes
+
+This preserves the explicit `?autoLogin=` flow for TokenPocket and other wallets, while making imToken robust when the deeplink opens the page without the query parameter.
