    Registrations

    Overview

    Registrations in FusionAuth are the link between Users and Applications.

    A User can have zero or more registrations. Each registration can have zero or more roles associated with it.

    The registrations API documents the allowed attributes of a User registration.

    If a User exists in a tenant and attempts to authenticate against an Application, but are not registered, the authentication will succeed but they will not be authorized.

    Attributes

    With advanced registration forms, you can customize the attributes of a registration. By default, registrations have the following attributes:

    Username Optional

    The username of the User for this registration only.

    Languages Optional

    A list of locales that give, in order, the User’s preferred languages. These are important for email templates and other localizable text. See Locales.

    Timezone Optional

    The User’s preferred timezone for this registration.

    Roles Optional

    The roles that the User has for this registration.
