Fix Mobile Sign-In Error

@AhteshamAK

The main issue here is not just adding another login button — it’s fixing the complete authentication flow so users can sign in reliably without breaking existing accounts. I’ll review the current Google/Facebook authentication implementation, identify why email confirmation callbacks are failing, and fix the OAuth flow including redirect handling, token validation, session persistence, and mobile-specific configuration for iOS/Android. Relevant experience: * Mobile app authentication flows (Google OAuth, Apple Sign-In, Firebase/Auth systems) * React Native / Flutter login integrations * Debugging production sign-in issues and release-blocking bugs I’ll keep the existing email-password login intact and make sure the updated authentication flow is tested properly before delivery. I can start immediately and provide a quick fix within the fixed $20 budget. Could you share the current app framework (React Native, Flutter, native iOS/Android) and the authentication provider being used? Best, Ahtesham

As an experienced and skilled mobile app developer with a deep understanding of the intricacies of popular Android and iOS platforms, I believe I am the perfect fit for your project. Not only have I dealt with API integrations including social media logins like Facebook, but I have also incorporated secure authentications such as Sign in with Apple into my past projects. Adding Sign in with Apple alongside your current Facebook login is a priority for you and I guarantee a seamless integration that won't compromise the existing email-password option. Moreover, I understand the importance of UI/UX and assure you that incorporating a quick UI toggle on the welcome screen would be hassle-free and intuitive for your users. On top of my track record with successful integrations, my devotion to delivering high-quality work within the agreed-upon timeframes has consistently distinguished me from others. At just 20 USD, you'll be getting not just effective problem-fixing but also a committed long-term partner for your mobile app development needs. Let's connect to discuss further!

Hey, the sign-in error after the email confirmation link is likely a mismatch between your deep link handler and the app's current auth state. I’ll trace the callback flow to ensure the token correctly triggers the session update without interfering with your existing email login. The real challenge is keeping the Apple and Facebook flows clean so they don't conflict with the Google fix. Does the app currently use a specific state manager to handle these authentication redirects?

Adding Sign in with Apple means wiring up native auth on both platforms and handling the different callback payloads, plus updating your backend to accept the new tokens. I’ve shipped this for music and social apps built on Flutter and React Native—Apple, Google, and Facebook in parallel—without breaking local email auth. For your Google sign-in issue, I’ll check the token exchange and email confirmation flow. Those bugs are usually from a misconfigured redirect URI or a backend-side change. Is the project Flutter, React Native, or something else? I can start this week if you clarify the stack and repo access. Pradeep

Posso corrigir o fluxo de autenticação do seu app móvel, adicionando Sign in with Apple e ajustando o login existente (Facebook, Google e e‑mail/senha) sem quebrar nada no fluxo atual. Já implementei integrações completas com Apple/Google/Facebook em apps React Native e Flutter. Se quiser, posso detalhar como estruturo um fluxo OAuth móvel ou como corrijo erros de callback em ambientes iOS/Android. Meu foco: • Integração completa do Sign in with Apple (SDK, tokens, callbacks, storage). • Correção do Google Sign‑In: verificação de link por e‑mail, callback quebrado e fluxo de confirmação. • Ajuste rápido da UI na tela de boas‑vindas. • Garantir compatibilidade com iOS/Android e manter o login por e‑mail funcionando. • Testes finais para garantir que todos os métodos de login estejam estáveis. Já corrigi fluxos idênticos em apps de produção. Posso entregar dentro do orçamento fixo de 20 USD.

Hi, You’re not just fixing logins here, you’re removing the friction that quietly breaks trust at the very first tap. I can update the authentication flow to add Sign in with Apple, keep Facebook Login stable, and fix the broken Google sign-in confirmation-link issue without disrupting the existing email-password path. I’ve handled mobile auth integrations before, including callback handling, token storage, and small UI adjustments that fit neatly into an existing release cycle. I’ll review the current sign-in flow, trace where the Google confirmation link is failing, implement the Apple/Facebook updates cleanly, and verify both iOS and Android behavior end-to-end. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you can share the current auth stack and the Google/Facebook/Apple config status, I can start quickly and keep the fix focused. Could you confirm whether the app uses Firebase Auth, custom API auth, or another backend flow for social login? Best regards, Asad

@arilrivenski

Hi, I hope you're doing well. I have hands-on experience adding OAuth providers and fixing sign-in flows in React Native apps, having delivered several similar builds. On a recent project I added Sign in with Apple using the react-native-apple-authentication module and fixed Google sign-in by replacing an outdated react-native-google-signin setup and restoring proper OAuth redirect handling (had to update SHA fingerprints and the backend token exchange). I'd start by reproducing the failing Gmail confirmation and testing deep-link/redirect URIs, then add Apple Sign-In on iOS and Android (using the native Apple SDK where required), and ensure token storage is consistent (SecureStore/Keychain). But first I'll read your auth logs to confirm the root cause. If you have ten minutes, I'd like to compare notes on the callback endpoints and the email confirmation workflow so I can prioritise the fixes. Thank you, Aril

@matthewm0615

Hi, I can add Sign in with Apple alongside your existing Facebook Login and fix the Google sign in confirmation link issue, without breaking your current email password flow. My approach would be to first integrate the Apple SDK with proper callback handling and secure token storage, add the UI toggle to your existing welcome screen to match current styling, then trace the Google confirmation link failure, likely a redirect URI or expired token issue, and verify all three sign in paths work cleanly together before handoff. Could you please answer the following question? I would appreciate your response. ✅ Is the app built in React Native or Flutter, since your skills list both and that changes which Apple and Google auth libraries I would use? ✅ When the Google confirmation link fails, does it show an error message or simply not respond, and is this on both iOS and Android or just one platform? I am ready to start immediately. Best regards, Matthew Moore
