What are the risks/drawbacks of logging in with Google?

Third-party apps and services are built by external developers and are not owned or operated by Google. So, when you connect them to your Google account, you are granting these apps or services access to use your account information. These authorized apps may use your account information, such as your name and profile picture, in various ways you have not consented to or understood.

Secondly, the centralized nature of these Single Sign On (SSO) systems means you are counting on a single source for all your password management, creating a single point of failure. If your Google account gets compromised, the other sites you use it to log in could be completely exposed.

This is one very good reason to ensure you have two-factor authentication set up on both your Google account and any other third-party sites that allow it.

Once you’ve disconnected them, the selected third-party apps and services won’t have access to your Google Account info, but you may need to contact them directly to request they delete the data they already have.

We would also recommend you regularly review third-party apps that have access to your account to confirm that you still want to give them access.
