We offer a contextual authentication API that really has one job and that's to tell you if a user is who you think they are. The answer we return must be on point as our customers will use it to make decisions, allow access, or process transactions within their applications. A question that comes up often is "how well does your system work with limited data?". In other words, how do we confirm identity and return a risk score for a user on the very first time we've seen them? A reliable answer to this question enables better user experiences, improved security, and assists in detecting fake or fraudulent new account registrations.
