Description

A service account is a special Google account that belongs to an application or a VM, instead of to an individual end-user. The application uses the service account to call the service's Google API so that users aren't directly involved. It's recommended not to use admin access for ServiceAccount.

Rationale

Service accounts represent service-level security of the Resources (application or a VM) which can be determined by the roles assigned to it. Enrolling ServiceAccount with Admin rights gives full access to an assigned application or a VM. A ServiceAccount Access holder can perform critical actions like delete, update change settings, etc. without user intervention. For this reason, it's recommended that service accounts not have Admin rights.

Impact

Removing *Admin or *admin or Editor or Owner role assignments from service accounts may break functionality that uses impacted service accounts. Required role(s) should be assigned to impacted service accounts in order to restore broken functionalities.

5. Identify User-Managed user created service account with roles containing *Admin or *admin or role matching Editor or role matching Owner under Role Column.
6. Click on Edit (Pencil Icon) for the Service Account, it will open all the roles which are assigned to the Service Account.
