What is a BT OneID?
BT OneID is another name for your BT.com username. You can link this username to other BT services that need a username and password for example, a BT Broadband Talk account. When you’ve linked your services, you can access them by logging in with your BT OneID. You can also move between your linked accounts without having to log in again. We’ll be adding more services to BT OneID in the future.
