Authenticating customers or employees at scale requires a different approach. The logistics involved in deploying the latest biometrics, FIDO2, or even legacy authenticators apps will fail to give enterprises the reach they need. Proof-of-possession of the mobile telephone number is the only core technology that can reach 5 billion mobile users with methods that are easily understood and adopted by users. Sinch is the only CPaaS (Communications Platform as a Service) able to integrate all mobile telephone proof of possession methods via a single API which allows enterprises to maximize security and minimize cost, all while delivering the best possible customer and employee authentication experiences. Together, Sinch and ForgeRock deliver robust 2FA at enterprise scale which allows ForgeRock customers to maximize conversion and reach all their users across the globe.
