Google sign-in on iOS

Set up Google Sign-In for your iOS app — create an iOS OAuth Client ID in Google Cloud Console and add it to your WordPress settings.

Google Sign-In on iOS uses your app’s bundle identifier instead of a SHA-1 fingerprint. You create an iOS OAuth Client ID in Google Cloud Console and add it to your WordPress settings alongside the Web and Android Client IDs.

You need a separate iOS Client ID for each bundle identifier — typically one for your release app and one for your test app.

Step 1 — Create an iOS OAuth Client ID in Google Cloud Console

1. Go to Google Cloud Console and open your project.
2. Navigate to APIs & Services → Credentials.
3. Click + Create Credentials → OAuth client ID.
4. Set Application type to iOS.
5. Enter a name (e.g. Blockli iOS Release).
6. Enter your Bundle ID — this must match your app’s bundle identifier exactly (e.g. com.example.myapp).
7. Click Create.

Repeat for your test bundle identifier (e.g. Blockli iOS Test).

Step 2 — Add the Client IDs to your WordPress settings

1. In your WordPress admin, open the Blockli plugin and go to Settings.
2. Scroll down to the Social Login section.
3. Check Enable Google sign-in if it is not already enabled.
4. Under Google client IDs, add your iOS Release and iOS Test Client IDs using the input field and the Add button.
5. Check Create WordPress users from verified social sign-ins if you want new users to be able to register through Google Sign-In. When this is off, social login only works for accounts that already exist in WordPress (matched by email or a previously linked account).
6. Save your settings.

Your Google client IDs list should now contain your Web, Android, and iOS Client IDs. The backend accepts any of them as a valid audience when verifying the token.

Verify

Install a test build on an iOS device and confirm the Google Sign-In button appears and completes without error. If sign-in fails, check:

• The bundle ID on the OAuth client ID matches the app build you are testing.
• The iOS Client ID has been added in WordPress → Blockli → Settings → Social Login.
• The Web Client ID is also in the list — it is required for backend token verification.
