Simpan dan kategorikan konten berdasarkan preferensi Anda.
Anda dapat mengintegrasikan Firebase Authentication dengan sistem autentikasi kustom, dengan
cara memodifikasi server autentikasi Anda untuk menghasilkan token bertanda tangan kustom ketika
pengguna berhasil login. Aplikasi Anda akan menerima token ini dan menggunakannya untuk melakukan autentikasi
dengan Firebase.
Klik Generate New Private Key di bagian bawah Firebase Admin SDK pada halaman Service Accounts.
Pasangan kunci umum/pribadi baru untuk akun layanan secara otomatis disimpan di komputer Anda. Salin file ini ke server autentikasi Anda.
Melakukan autentikasi dengan Firebase
Impor modul FirebaseCore dalam
UIApplicationDelegate Anda, serta semua
modul Firebase lainnya yang digunakan oleh delegasi aplikasi Anda.
Misalnya, untuk menggunakan Cloud Firestore dan Authentication:
Konfigurasikan instance bersama FirebaseApp di metode application(_:didFinishLaunchingWithOptions:) delegasi aplikasi Anda:
SwiftUI
// Use Firebase library to configure APIsFirebaseApp.configure()
Swift
// Use Firebase library to configure APIsFirebaseApp.configure()
Objective-C
// Use Firebase library to configure APIs[FIRAppconfigure];
Jika menggunakan SwiftUI, Anda harus membuat delegasi aplikasi dan menambahkannya ke struct App melalui UIApplicationDelegateAdaptor atau NSApplicationDelegateAdaptor. Anda juga harus menonaktifkan swizzling delegasi aplikasi. Untuk mengetahui informasi lebih lanjut, baca petunjuk SwiftUI.
SwiftUI
@mainstructYourApp:App{// register app delegate for Firebase setup@UIApplicationDelegateAdaptor(AppDelegate.self)vardelegatevarbody:someScene{WindowGroup{NavigationView{ContentView()}}}}
Ketika pengguna login ke aplikasi Anda, kirim kredensial login mereka (misalnya, nama pengguna dan sandi) ke server autentikasi. Server
Anda akan memeriksa kredensial dan menampilkan
token khusus
jika kredensial tersebut valid.
Setelah Anda menerima token kustom dari server autentikasi, teruskan token tersebut
ke signInWithCustomToken agar pengguna dapat login:
Setelah pengguna login untuk pertama kalinya, akun pengguna baru akan dibuat dan ditautkan ke kredensial, yaitu nama pengguna dan sandi, nomor telepon, atau informasi penyedia autentikasi, yang digunakan pengguna tersebut untuk login. Akun baru ini disimpan sebagai bagian dari project Firebase Anda, dan dapat digunakan untuk mengidentifikasi pengguna di setiap aplikasi dalam project, terlepas dari cara pengguna login.
Di aplikasi, Anda bisa mendapatkan informasi profil dasar pengguna dari objek User. Baca bagian Mengelola Pengguna.
Di Aturan KeamananFirebase Realtime Database dan Cloud Storage, Anda bisa
mendapatkan ID pengguna unik milik pengguna yang login dari variabel auth,
dan menggunakannya untuk mengontrol data yang dapat diakses oleh pengguna.

Your app receives this token and uses it to authenticate\nwith Firebase.\n\nBefore you begin\n\n1. [Create a Firebase project and register your app](/docs/ios/setup) if you haven't already.\n2. Use Swift Package Manager to install and manage Firebase dependencies.\n\n | Visit [our installation guide](/docs/ios/installation-methods) to learn about the different ways you can add Firebase SDKs to your Apple project, including importing frameworks directly and using CocoaPods.\n 1. In Xcode, with your app project open, navigate to **File \\\u003e Add Packages**.\n 2. When prompted, add the Firebase Apple platforms SDK repository: \n\n ```text\n https://github.com/firebase/firebase-ios-sdk.git\n ```\n | **Note:** New projects should use the default (latest) SDK version, but you can choose an older version if needed.\n 3. Choose the Firebase Authentication library.\n 4. Add the `-ObjC` flag to the *Other Linker Flags* section of your target's build settings.\n 5. When finished, Xcode will automatically begin resolving and downloading your dependencies in the background.\n3. Get your project's server keys:\n 1. Go to the [Service Accounts](https://console.firebase.google.com/project/_/settings/serviceaccounts/adminsdk) page in your project's settings.\n 2. Click *Generate New Private Key* at the bottom of the *Firebase Admin SDK* section of the *Service Accounts* page.\n 3. The new service account's public/private key pair is automatically saved on your computer. Copy this file to your authentication server.\n\nAuthenticate with Firebase\n\n1. Import the `FirebaseCore` module in your `UIApplicationDelegate`, as well as any other [Firebase modules](/docs/ios/setup#available-pods) your app delegate uses. For example, to use Cloud Firestore and Authentication: \n\n SwiftUI \n\n ```swift\n import SwiftUI\n import FirebaseCore\n import FirebaseFirestore\n import FirebaseAuth\n // ...\n \n ```\n\n Swift \n\n ```swift\n import FirebaseCore\n import FirebaseFirestore\n import FirebaseAuth\n // ...\n \n ```\n\n Objective-C \n\n ```objective-c\n @import FirebaseCore;\n @import FirebaseFirestore;\n @import FirebaseAuth;\n // ...\n \n ```\n2. Configure a [`FirebaseApp`](/docs/reference/swift/firebasecore/api/reference/Classes/FirebaseApp) shared instance in your app delegate's `application(_:didFinishLaunchingWithOptions:)` method: \n\n SwiftUI \n\n ```swift\n // Use Firebase library to configure APIs\n FirebaseApp.configure()\n ```\n\n Swift \n\n ```swift\n // Use Firebase library to configure APIs\n FirebaseApp.configure()\n ```\n\n Objective-C \n\n ```objective-c\n // Use Firebase library to configure APIs\n [FIRApp configure];\n ```\n3. If you're using SwiftUI, you must create an application delegate and attach it to your `App` struct via `UIApplicationDelegateAdaptor` or `NSApplicationDelegateAdaptor`. You must also disable app delegate swizzling. For more information, see the [SwiftUI instructions](/docs/ios/learn-more#swiftui). \n\n SwiftUI \n\n ```swift\n @main\n struct YourApp: App {\n // register app delegate for Firebase setup\n @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate\n\n var body: some Scene {\n WindowGroup {\n NavigationView {\n ContentView()\n }\n }\n }\n }\n \n ```\n4. When users sign in to your app, send their sign-in credentials (for example, their username and password) to your authentication server. Your server checks the credentials and returns a [custom token](/docs/auth/admin/create-custom-tokens) if they are valid.\n5. After you receive the custom token from your authentication server, pass it to `signInWithCustomToken` to sign in the user: \n\n Swift \n\n ```swift\n Auth.auth().signIn(withCustomToken: customToken ?? \"\") { user, error in\n // ...\n }\n ```\n\n Objective-C \n\n ```objective-c\n [[FIRAuth auth] signInWithCustomToken:customToken\n completion:^(FIRAuthDataResult * _Nullable authResult,\n NSError * _Nullable error) {\n // ...\n }];\n ```\n\nNext steps\n\nAfter a user signs in for the first time, a new user account is created and\nlinked to the credentials---that is, the user name and password, phone\nnumber, or auth provider information---the user signed in with. This new\naccount is stored as part of your Firebase project, and can be used to identify\na user across every app in your project, regardless of how the user signs in.\n\n- In your apps, you can get the user's basic profile information from the\n [`User`](/docs/reference/ios/firebaseauth/interface_f_i_r_user) object. See [Manage Users](/docs/auth/ios/manage-users).\n\n- In your Firebase Realtime Database and Cloud Storage\n [Security Rules](/docs/database/security/user-security), you can\n get the signed-in user's unique user ID from the `auth` variable,\n and use it to control what data a user can access.\n\nYou can allow users to sign in to your app using multiple authentication\nproviders by [linking auth provider credentials to an\nexisting user account.](/docs/auth/ios/account-linking)\n\nTo sign out a user, call [`signOut:`](/docs/reference/ios/firebaseauth/interface_f_i_r_auth#ab0d5111f05c3f1906243852cc8ef41b1). \n\nSwift \n\n```swift\nlet firebaseAuth = Auth.auth()\ndo {\n try firebaseAuth.signOut()\n} catch let signOutError as NSError {\n print(\"Error signing out: %@\", signOutError)\n}\n```\n\nObjective-C \n\n```objective-c\nNSError *signOutError;\nBOOL status = [[FIRAuth auth] signOut:&signOutError];\nif (!status) {\n NSLog(@\"Error signing out: %@\", signOutError);\n return;\n}\n```\n\nYou may also want to add error handling code for the full range of authentication\nerrors. See [Handle Errors](/docs/auth/ios/errors)."]]
