CIBA
An acronym for Client-Initiated Backchannel Authentication. For more details about it please take a look at the official specification: OpenID Connect Client Initiated Backchannel Authentication Flow Please note it is a cross-device protocol and SHOULD not be used for same-device scenarios. If the Consumption Device and Authorization Device are the same device, protocols like OpenID Connect Core OpenID.Core and OAuth 2.0 Authorization Code Grant as defined in RFC6749 are more appropriate.
