You can first visit the Google homepage and click the “Sign In” button in the top right corner. After entering your email address and password, the system will take you to the account homepage. You can find various settings options in “Manage your Google Account.” Gmail Business Email offers rich features and security protections, allowing you to manage account information more effectively.

If you want to find your account number, you can check it on the Google Account settings page. Different services have different identification methods. For example, in Gmail, you mainly see your username and email address; in YouTube, you have a unique user ID; in Google Analytics, GA3 uses Client ID to identify devices, while GA4 uses User-ID to track the same user’s behavior across devices. You can find relevant account identification information on the “Personal Info” or “Security” pages based on the service type. This information helps you manage third-party app logins and account security.
Google’s different services have unique account identification methods. GA3 automatically generates a Client ID, representing each device or browser; GA4 requires you to set up a User-ID to track the same user’s behavior across multiple devices. Gmail and YouTube primarily use usernames or email addresses. You can use the “Sign in with Google” feature to centrally manage account information for multiple third-party apps. This enhances security and makes it easier for you to look up and confirm your account information later.
