Google Cloud IAM Members: In Google Cloud IAM, members can be individuals or entities that

interact with Google Cloud resources. These members are assigned roles that grant them

permissions to perform specific actions1.

Identity Types: The identities used by IAM members to access Google Cloud resources are typically

email addresses or domain names, depending on the type of member1.

Email Address as Identity: For a Google Account, Google group, and service account, the identity is

generally an email address. This email address is used to uniquely identify the member within

Google Cloud’s IAM system1.

Domain Name as Identity: For G Suite and Cloud Identity domains, the identity is the domain name

associated with the organization’s account. This domain name represents the collective identity of

the organization within Google Cloud1.

Access to Resources: IAM members use these identities to authenticate and gain access to Google

Cloud resources as per the permissions defined by their assigned roles1.
