When you no longer need a service account on one particular project, you can end the association without deleting the account.
Note: Only an Organization Administrator can remove a service
account.
-
Select Projects on the left-hand menu.
-
Choose a project.
-
Click Settings.
-
On the left-hand menu, select Service Accounts.
-
Identify the account in question, using the Search by
Name text field at the top right, if needed.
-
Remove the service account from the project by clicking the trash can icon to
the right of the project name.
This does not delete the service account, but removes the association with the
project.
