Cloud accounts · Custom Google sign-in credentials
Are my custom Google credentials shared with Storage Studio?
Short answer: No. Your Client ID and Client Secret stay on your Mac and are only used to sign in with Google. You own the project in Google's console and can delete or replace the credentials whenever you like.
No. The Client ID and Client Secret you paste stay on your Mac and are only used to sign in with Google. They aren't sent to Storage Studio's servers.
Because the credentials belong to your own Google Cloud project, you can also delete or replace them in Google's console at any time; an account signed in with deleted credentials will need adding again.
