A leading area of innovation is in adaptive authentication. This technology determines the level of authentication needed for a given interaction with a service. So, each interaction comes with a specified level of authentication that best fits the level of the transaction, balancing effective security with degree of inconvenience for users.

With adaptive authentication, each interaction with a device and service is effectively graded for its normalcy, based on prior user behavior. Data points like geography, time, and watching behavior are taken into consideration to determine this grade. Grading ensures that interactions that need a high level of security receive it while routine interactions allow users a frictionless experience.
