!!! Overview
[{$pagename}] ([CIBA]) is a [specification] written by [MODRNA] [Working Group] of [OpenID Foundation] defines a new [OAuth 2.0] [Grant Type] where user consent can be requested through an [Out of Band Request] flow..
[{$pagename}] public review period for the [specification] started on Dec. 14, 2018 and it was approved on Feb. 4, 2019.
[CIBA] flows, the [Authorization Server] delegates the tasks of [End-User] [authentication] and [consent] confirmation to an [authentication] [device] of the end-user. A [smartphone|Mobile Device] is a typical [example] of authentication devices. This process is performed on the background after a response is returned from the backchannel [authentication] [endpoint] to the [OAuth Client] [application].
[{$pagename}] flows allows the [OAuth Client] [application] is not under the control of the [End-User] and it can be physically separated from the [authentication] device. For example, [CIBA] can support a use case where a [OAuth Client] application is running on a computer in front of an operator working in a call center in Okinawa, while end-user authentication and consent confirmation are performed on a smartphone at the hand of the end-user who has made the call to the call center from Tokyo.
[{$pagename}] allows the ability to complete the [authorization], the user can receive a push [Notification] sent to the financial institution’s native mobile app running on the user’s phone, allowing the customer to avoid confusing [Redirection] via web [browsers].
!! [Financial API] ([FAPI]) [{$pagename}]
There is also a [FAPI] version of [{$pagename}] that supports this decoupled interaction method. The [CIBA] spec allows a client that gains knowledge of an identifier for the user to obtain [tokens] from the [Authorization Server]. The user consent is given at the user's Authentication Device mediated by the [Authorization Server]. This document profiles the CIBA specification to bring it in line with the other [FAPI] parts and provides security recommendations for its use with [APIs] that require [financial-grade security|Financial API].
Although it is possible to code an [OpenID Connect Provider] and [Relying Party] from first principles using this specification, the main audience for this specification is parties who already have a certified [implementation] of [OpenID Connect] and want to achieve a higher level of security. Implementors are encouraged to understand the security considerations contained in section 7.5 before embarking on a 'from scratch' [implementation].
[{$pagename}] makes [app2app] possible.
