Integration detail

tru.ID SIM-based verification


tru.ID is a SIM-based possession factor. tru.ID enables businesses of all sizes to create passwordless, phishing-resistant login journeys by adding SIM-based verification. All users in your Okta directory who use Okta for single sign-on, can be verified by tru.ID in real-time to prove possession of a mobile digital identity. You can use tru.ID on its own to deploy passwordless login policies, or prove mobile possession in your existing login flow.
