The short answer
ZoopCoder adds social login with up to 2 providers from Google, Facebook and Apple to one existing website or one Android, iOS or Flutter app for a fixed ₹3,499, tested end to end in 2-4 working days. Apple App Review guideline 4.8 expects an app that signs users in with a third-party account such as Google or Facebook to also offer an equivalent login that limits data to name and email, lets the user hide their email and does not track them, and Sign in with Apple is the usual way to meet it. Apple returns the user's name and email only the first time they approve the app, so the integration has to save them on that first sign-in.
What you get
- Your existing login and user table reviewed, and the safest way to link social accounts to existing users by verified email agreed with you
- Up to 2 providers set up from Google, Facebook and Sign in with Apple: the developer-console configuration, redirect URLs and the sign-in button in your design
- Sign-in and sign-up through each provider, logout, and a link to an existing account when the verified email already exists
- Apple handled properly: name and email saved on the first sign-in, and private-relay email addresses supported
- Your Google consent screen moved out of Testing so real users, not just 100 listed testers, can sign in
- Tested on a staging copy with fresh and existing accounts, then switched on in production
- A short note on the keys, redirect URLs and the dates when any key expires

About this service
Social login looks like a button, but most of the work is behind it: the provider console settings, the exact redirect URLs, what to do when the same person signs in with a different method, and what each platform quietly requires. Each provider has its own trap. Google blocks everyone beyond 100 listed testers while the consent screen stays in Testing. Facebook only lets people with a role in the app sign in until the app is switched to live mode. Apple needs a Services ID for the web and a client secret that is a signed token with a maximum life of six months, so it has to be renewed or the button silently stops working. We configure each one, write down every expiry date and test with brand-new and existing accounts, so launch day is not the first real test.
Questions before you buy
Do I have to offer Sign in with Apple?
Apple's guideline 4.8 requires an app that uses a third-party login to also offer an equivalent privacy-focused login option. Sign in with Apple is the usual choice and is accepted without further argument. Apps that only use their own accounts are not affected. App Review decides, so we build to the written rule and cannot guarantee approval.
Will my existing users be able to sign in with Google?
Yes. When the verified email from Google matches an existing account we link the two, so nobody ends up with a duplicate account or loses their data. We agree the exact rule with you first.
Does this work for a mobile app and a website?
It covers one of them per order, either one website or one Android, iOS or Flutter app. If you need the same login on both, order each separately and we reuse the same provider setup.
Why did Facebook login stop working for everyone except me?
Almost always the Meta app is still in development mode, where only people with a role in the app can sign in. Switching it live needs a privacy policy URL and a few settings, which we do as part of this service.
What does it cost to run?
Google, Facebook and Apple do not charge for sign-in itself. Apple requires an Apple Developer Program membership, which is a yearly fee paid to Apple.
Can you add login to a WordPress site?
Not in this service, which is for custom websites and apps. WordPress sites usually need a plugin configured instead; ask us on WhatsApp and we will tell you what applies.
