In a market where there are multiple Identity Providers, Identity Brokers will act as an intermediary between Organisations and Identity Providers. They allow organisations to enter into a single contract to consume identities from multiple identity providers. They will often provider selector screens to allow the user to choose which identity provider to use to with an organisation. Brokers may act as a commercial agent, agreeing prices with Identity Providers and then selling the IDs on to Organisations at a margin.
