Identity Broker is a system that can support Bring-Your-Own-Identity (BYOI) schemes by taking a users existing identity and allowing them to authenticate to unaffiliated websites using that identity. Biometrics include fingerprint scanners and iris scanners built into native apps for consumer or enterprise authentication. Single-tap push authentication lets users authenticate with a tap of a button on a mobile device, and is offered by both consumer services and enterprises. Single Sign On (SSO) solutions, wherever possible, can eliminate this frustration by providing the capability to. authenticate once, and be subsequently and automatically authenticated when accessing various resources.”]
