Ringkasan

OAuth-based App Flip Linking (App Flip) allows your users to easily and quickly link their accounts in your authentication system to their Google accounts. If your app is installed on your user’s phone when they initiate the account linking process, they are seamlessly flipped to your app to obtain user authorization.

This approach provides a faster and easier linking process since the user does not have to re-enter their username and password to authenticate; instead, App Flip leverages the credentials from the user's account on your app. Once a user has linked their Google account with your app, they can take advantage of any integrations that you have developed.

You can set up App Flip for both iOS and Android apps.

This figure shows the steps for a user to link their Google account to your authentication system. The first screenshot shows how a user can select your app if their Google account is linked to your app. The second screenshot shows the confirmation for linking their Google account with your app. The third screenshot shows a successfully linked user account in the Google app.

Requirements

To implement App Flip, you must fulfill the following requirements:

  • You must have an Android or iOS app.
  • You must own, manage and maintain an OAuth 2.0 server which supports the OAuth 2.0 authorization code flow.

Design guidelines

This section describes the design requirements and recommendations for the App Flip account linking consent screen. After Google calls your app, your app displays the consent screen to the user.

Requirements

  1. You must communicate that the user’s account is being linked to Google, not to a specific Google product, such as Google Home or Google Assistant.

Recommendations

We recommend that you do the following:

  1. Display Google's Privacy Policy. Include a link to Google’s Privacy Policy on the consent screen.

  2. Data to be shared. Use clear and concise language to tell the user what data of theirs Google requires and why.

  3. Clear call-to-action. State a clear call-to-action on your consent screen, such as “Agree and link.” This is because users need to understand what data they're required to share with Google to link their accounts.

  4. Ability to cancel. Provide a way for users to go back or cancel, if they choose not to link.

  5. Ability to unlink. Offer a mechanism for users to unlink, such as a URL to their account settings on your platform. Alternatively, you can include a link to Google Account where users can manage their linked account.

  6. Ability to change user account. Suggest a method for users to switch their account(s). This is especially beneficial if users tend to have multiple accounts.

    • If a user must close the consent screen to switch accounts, send a recoverable error to Google so the user can sign in to the desired account with OAuth linking and the implicit flow.

  7. Include your logo. Display your company logo on the consent screen. Use your style guidelines to place your logo. If you wish to also display Google's logo, see Logos and trademarks.

This figure shows an example consent screen with call-outs to the individual requirements and recommendations to be followed when you design a user consent screen.

Menyiapkan App Flip berbasis OAuth

Bagian berikut menjelaskan prasyarat untuk App Flip berbasis OAuth dan cara mengonfigurasi project App Flip di konsol Actions.

Buat Action dan siapkan server OAuth 2.0

Sebelum dapat mengonfigurasi App Flip, Anda perlu melakukan hal berikut:

Mengonfigurasi App Flip di konsol Actions

Bagian berikut menjelaskan cara mengonfigurasi App Flip di konsol Actions.

  1. Klik Develop di navigasi atas. Selanjutnya, klik Penautan akun di navigasi sebelah kiri.
  2. Aktifkan tombol di samping Penautan akun.
  3. Di bagian Pembuatan akun, pilih Tidak, saya hanya ingin mengizinkan pembuatan akun di situs saya.
  4. Klik Next.
  5. Di bagian Jenis penautan, pilih OAuth dan Kode otorisasi dari menu drop-down.
  6. Klik Next.
  7. Isi semua kolom di bagian Informasi Klien OAuth. (Jika App Flip tidak didukung, OAuth reguler akan digunakan sebagai penggantian.)
  8. Klik Next.
  9. Di bagian Gunakan aplikasi untuk penautan akun (opsional), centang Aktifkan untuk iOS.
  10. Isi kolom Link Universal. Untuk informasi selengkapnya tentang link universal, lihat Mengizinkan Aplikasi dan Situs untuk Ditautkan ke Konten Anda .
  11. Jika Anda ingin mengonfigurasi klien secara opsional, tambahkan cakupan, lalu klik Tambahkan cakupan di bagian Konfigurasi klien Anda (opsional). Jika belum, klik Next.
  12. Di bagian Petunjuk pengujian, ketik test (atau string lainnya) sebagai placeholder. (Mengisi kolom ini dengan akun pengujian hanya diperlukan jika Anda benar-benar mengirimkan Action untuk dipublikasikan.)
  13. Klik Simpan.

Sekarang Anda dapat melanjutkan ke bagian berikutnya untuk menerapkan App Flip di aplikasi iOS atau Android.

Menerapkan App Flip di aplikasi native

Untuk menerapkan App Flip, Anda perlu mengubah kode otorisasi pengguna di aplikasi untuk menerima deep link dari Google.

Menguji App Flip di perangkat Anda

Setelah membuat Action dan mengonfigurasi App Flip di konsol dan aplikasi, Anda dapat menguji App Flip di perangkat seluler. Anda dapat menggunakan aplikasi Asisten Google untuk menguji App Flip.

Untuk menguji App Flip dari aplikasi Asisten, ikuti langkah-langkah berikut:

  1. Buka Konsol Actions, lalu pilih project Anda.
  2. Klik Test di navigasi atas.
  3. Picu alur penautan akun dari aplikasi Asisten:
    1. Buka aplikasi Asisten Google.
    2. Klik Setelan.
    3. Di tab Asisten, klik Kontrol Rumah.
    4. Klik Tambahkan(+).
    5. Pilih Action Anda dari daftar penyedia. Parameter ini akan diawali dengan “[test]” dalam daftar. Saat Anda memilih Action [pengujian] dari daftar, aplikasi Anda akan terbuka.
    6. Pastikan aplikasi Anda sudah diluncurkan dan mulai uji alur otorisasi Anda.
