사용자나 애플리케이션이 데이터베이스 인스턴스에 연결한 후 사용자나 애플리케이션은 사용자 또는 서비스 계정으로 로그인해야 합니다.
Cloud SQL 인스턴스를 만들 때 기본 사용자(루트) 계정을 설정합니다. 또한 더 많은 사용자를 만들어 인스턴스에 대한 액세스를 보다 세밀하게 제어할 수 있습니다.

You must configure both levels of access control before you can\nmanage your instance.\n\nLevels of access control\n------------------------\n\nConfiguring access control involves controlling who or\nwhat can access the instance. Access control occurs on two levels:\n\nInstance-level access\n:\n Instance-level access authorizes access to your Cloud SQL instance\n from an application or client (running on an App Engine standard environment or externally)\n or from another Google Cloud service, such as Compute Engine.\n\nDatabase access\n:\n Database access uses\n [PostgreSQL roles](https://www.postgresql.org/docs/current/static/user-manag.html) to allow PostgreSQL users to have access to the data\n in your instance.\n| **Note:** For information about controlling\n| who can *manage* your instance, see\n| [Project access control](/sql/docs/project-access-control).\n\n\u003cbr /\u003e\n\n### Instance-level access\n\nHow you configure instance-level access depends on where you are connecting from:\n\n### Database access\n\nAfter a user or application connects to a database instance, the user or\napplication must log in with a user or service account.\n\nAs part of creating a Cloud SQL instance, you set up the default user\n(root) account. You can also create more users to give you finer-grained control\nover access to your instance.\n\nFor more information,\nsee [PostgreSQL users](/sql/docs/postgres/users) and\n[Creating and managing PostgreSQL users](/sql/docs/postgres/create-manage-users).\n\nWhat's next\n-----------\n\n- Learn more about [how Cloud SQL works with PostgreSQL users](/sql/docs/postgres/users).\n- Learn more about [PostgreSQL roles](https://www.postgresql.org/docs/current/static/user-manag.html).\n- Learn more about your [options for connecting from an external application](/sql/docs/postgres/connect-overview).\n- Learn about [controlling who can manage your Google Cloud Platform project](/sql/docs/postgres/roles-and-permissions)."]]
