Account security recommender
The account security recommender prompts Google Cloud project owners to protect their account with their phone's built-in security key. If a project owner has an eligible device associated with their account and isn't using a third party Identity provider for single sign-on, a notification shows in console's Notifications menu. The project owner can then choose to enable their phone as a security key for their account, or dismiss the notification.
Certain roles can opt out of this recommender for the organization.
