This plugin provides a Google account login option for a website, primarily for administrators who want to simplify user access. It is suitable for teams, agencies, or membership sites where users already have Google accounts.

• Google OAuth Integration: Implements secure login using Google's OAuth 2.0 system, requiring setup of a project in the Google Developer Console.
• Domain Restriction: Limits account creation and login to users from specific email domains, useful for internal or closed communities.
• Automatic Account Creation: Generates a new user account on the site when a person from an approved domain logs in for the first time.
• Existing Account Linking: Allows users who already have a traditional website account to connect it to their Google profile.
• Hidden Login Parameter: Supports a custom URL parameter that can trigger an automatic login or redirect for authenticated Google users.
