# Praecise account

> One Praecise account for every product: sign people in with it, confirm an action with a passkey, be told when they sign out, and manage an account's domains and mailboxes. It is an OpenID Connect provider at https://accounts.praecise.com; a product has no sign-in of its own and sends people here.
