外掛說明
WP One Tap Google Sign In adds Google One Tap authentication to WordPress. It helps site owners offer a faster, passwordless login experience while keeping authentication tied to existing WordPress user accounts.
When a visitor signs in with Google, the plugin verifies the Google ID token server-side, checks the configured OAuth client ID, confirms the Google email is verified, and then signs in the matching WordPress user. The plugin also supports site-wide display for logged-out visitors, a customizable companion message block, and direct Google account linking from WordPress user profiles.
Key Features
- Google One Tap prompt on the WordPress login screen.
- Optional site-wide One Tap prompt for logged-out visitors.
- Server-side Google ID token verification with WordPress HTTP APIs.
- Existing-user login only by default.
- Google account linking and disconnect controls on WordPress user profiles.
- Automatic account-link migration after a successful verified email login.
- Admin activity log for successful logins, failed attempts, account linking, and unlinking events.
- Salted hashes for IP addresses and Google account identifiers in the activity log.
- Optional custom message block with image, title, and formatted content.
- WordPress 7.0-ready metadata with PHP 8.1, 8.2, and 8.3 compatibility.
Security Approach
The plugin uses WordPress nonces for AJAX requests, sanitizes all incoming data, escapes admin output, and validates the Google token audience against the configured OAuth client ID. It does not create new users automatically. A Google login succeeds only when the verified Google account maps to an existing WordPress user.
Privacy
The activity log stores the Google email address used during an event, the WordPress user ID when available, event status, event reason, user agent, and salted hashes of the request IP address and Google account identifier. Activity records older than 90 days are pruned automatically when new events are logged.
Configuration

- Find the Google One Tap Sign-In section.
- Use the Google button to link a verified Google account.
- To disconnect, check Disconnect this Google account and save the profile.
Customize the Message Block
- Go to Settings > One Tap GSI.
- Enable the custom message block.
- Choose an image from the Media Library or enter an image URL.
- Add a short title and supporting formatted content.
- Save the settings.

常見問題集
-
Does this plugin create new WordPress users?
-
No. WP One Tap Google Sign In signs in existing WordPress users only. It does not automatically register new users.
-
Can users disconnect their Google account?
-
Yes. Users can disconnect the linked Google account from their WordPress profile. Administrators with permission to edit users can also manage the link for other accounts.
-
What happens if a user changes their Google email address?
-
After account linking, the plugin uses Google’s stable account identifier for future logins. This is more reliable than email-only matching.
-
Where can I view login attempts?
-
Go to Settings > One Tap GSI Activity to review recent sign-in, linking, and unlinking events.
-
Does the plugin store raw IP addresses?
-
No. The plugin stores a salted hash of the request IP address for correlation in security reviews.
-
Is this compatible with WordPress 7.0 and modern PHP?
-
The plugin metadata targets WordPress 7.0 and PHP 8.1 or higher. The code avoids dynamic properties, deprecated Google client dependencies, and older PHP patterns that commonly cause warnings on PHP 8.2 and PHP 8.3.
