I am an account owner and have an authorised user on my account, but I do not wish them to be able to share data on my account. How do I ensure this?
An authorised user on your account cannot automatically share data on your account via Open Banking. As the account owner, you can control whether you enable them to share data or not. They will default to not being able to share data. To check who is enabled to share data on your account, view the Manage Data Sharing dashboard in internet banking.
