When you verify your domain during a Chrome Enterprise trial setup, you establish ownership and control over the domain within Google's systems. This is a crucial step in identity management as it allows you to:

Manage user accounts: Create, edit, and delete user accounts within the domain, ensuring control over who can access company resources.

Apply security policies: Enforce security policies like password requirements, two-factor authentication, and access controls for users within the domain.

Single Sign-On (SSO): Enable seamless and secure single sign-on for users across various Google services and other integrated applications.

By verifying the domain, you essentially gain centralized control over user identities and their access to resources, which is a core aspect of identity management.
