Google AI Studio + login
Google AI Studio apps typically use Firebase Auth or Google Identity, if your app needs accounts. Email and password login works unchanged inside a WebViewGold app. Google and other OAuth providers block embedded WebViews, and Apple adds a rule of its own. Here is how to make every login method work in the app without changing your auth code.
From $109 one-time per platform, or let our team do it all from $698.
Google refuses OAuth inside embedded WebViews. WebViewGold's Social Login Helper detects the Google (and Facebook) login URL and runs that step in a dedicated login window with an accepted user agent, then returns to your app. One setting, no changes in Google AI Studio.
If the iOS app offers Google, Facebook or GitHub login, Apple requires an equivalent privacy-friendly option, typically Sign in with Apple. Enable the Apple provider in Firebase Auth or Google Identity, if your app needs accounts, add the button, and WebViewGold handles the appleid.apple.com flow automatically.
Email magic links and password resets open in Safari or Chrome instead of the app. Universal Links (iOS) and App Links (Android) in WebViewGold route links to your domain into the app and keep the session there.
Paste this into Google AI Studio to implement the web-app side. Review the result, publish, then test inside the WebViewGold app.
Prepare Firebase authentication in this Gemini app for the WebViewGold wrapper. In the Firebase Auth login screen add a Continue with Apple button next to Google. In the Cloud Run server, serve GET /.well-known/apple-app-site-association and GET /.well-known/assetlinks.json as application/json with placeholders TEAM_ID, BUNDLE_ID, PACKAGE_NAME and SHA256_FINGERPRINT. Add POST /api/account/delete that verifies the Firebase ID token, deletes the user's Firestore documents including stored Gemini conversations, calls the Admin SDK deleteUser, and returns 204; add a confirmed Delete my account button in settings that calls it and signs out. Keep an email option visible. Make sure no Gemini API key is used in the client bundle.
My iOS WebView is finally approved. Thanks!!
About 30 minutes, mostly in the store dashboards.
In Config.swift set google_login_helper_triggers (accounts.google.com) and facebook_login_helper_triggers; on Android use GOOGLE_LOGIN_HELPER_TRIGGERS in Config.java. Test the login inside the app.
Create a Services ID and key in the Apple Developer portal, enable the Apple provider in Firebase Auth or Google Identity, if your app needs accounts and add a "Continue with Apple" button next to Google. Nothing to configure in WebViewGold.
Host the apple-app-site-association and assetlinks.json files on your domain, enable Universal Links / App Links in WebViewGold and make sure the auth redirect URL in Firebase Auth or Google Identity, if your app needs accounts points to your domain. See the deep-link guide.
Apple (5.1.1) and Google require in-app account deletion for apps with sign-up. Add a Delete account button that calls a backend function. See the account deletion guide.
In App Store Connect (App Review Information) and the Play Console (App access) enter test credentials so reviewers can see the logged-in experience.
bioauth://). Gate the app on launch or protect sensitive screens.No. The Social Login Helper works on the native side by detecting the OAuth URLs. The only additions are the Sign in with Apple provider (required by Apple if you offer other social logins) and, for magic links, the domain files for Universal Links.
Only if your iOS app offers a third-party login such as Google, Facebook or GitHub. If users can only sign in with email and password or magic link, Guideline 4.8 does not apply.
Google blocks OAuth in embedded WebViews for security reasons (the host app could read the credentials). The Social Login Helper runs the Google step in a trusted window that Google accepts and hands the session back to your app.
Yes. WebViewGold persists cookies and local storage, so Firebase Auth or Google Identity, if your app needs accounts sessions behave as in the browser.
Same result, different amount of work on your side. All three come with the approval guarantee and 24/7 human support.
