A Bang & Olufsen account allows you to manage your products and allows for additional services.
In the app, your account gives you a complete overview of your Bang & Olufsen products, and lets you know when product software updates are available. You can use the same account to sign in to the Bang & Olufsen app on all your mobile devices.
The account is a household account not a personal account and profiles will be supported soon. For now the account credentials will have to be shared with the members of the household.
