External services

This plugin connects to external identity services only when the site owner enables them. When Google One Tap is enabled, Google Identity Services may be loaded for logged-out visitors before they choose to sign in.

• The browser downloads the Google Identity Services library from https://accounts.google.com/gsi/client when a login button is displayed. The site’s OAuth Client ID and standard browser request information are sent to Google.
• After the visitor chooses a Google account, Google returns a signed identity token to the website. The token contains the account identifier and basic profile fields approved by the visitor.
• The server periodically downloads public signing keys from https://www.googleapis.com/oauth2/v3/certs to verify tokens. No visitor identity data is sent when public keys are downloaded.

This service is provided by Google under the Google APIs Terms of Service and Google Privacy Policy.

For enabled OAuth providers, the visitor is sent to the provider’s authorization page. The plugin sends the application Client ID, callback URL, requested basic-profile/email scopes, and a random state value. The provider sends an authorization code back to the website. The server exchanges that code and requests the visitor’s identifier, name, verified email and optional profile image.

• Facebook endpoints use facebook.com and graph.facebook.com. Meta Platform Terms and Meta Privacy Policy.
• LinkedIn endpoints use linkedin.com and api.linkedin.com. LinkedIn API Terms and LinkedIn Privacy Policy.
• Microsoft endpoints use login.microsoftonline.com and graph.microsoft.com. Microsoft APIs Terms and Microsoft Privacy Statement.
• Apple endpoints use appleid.apple.com. The plugin also downloads Apple’s public signing keys to validate ID tokens. Sign in with Apple terms and Apple Privacy Policy.

Privacy

When a visitor uses a social provider, that provider returns an account identifier and basic profile fields such as name, verified email address and profile image. The plugin stores the provider account identifier and profile image URL in WordPress user metadata. WordPress core stores the user’s name and email as part of the user account.

The browser loads Google’s Identity Services JavaScript from accounts.google.com when Google login is configured. Other providers are contacted only when their button is selected. Site owners should disclose enabled external services in their privacy policy and obtain any consent required in their jurisdiction.

Plugin metadata is available through WordPress personal-data export and erasure tools.
