Secure cloud-based and hybrid authentication

Multi-factor authentication
IT admins can require multi-factor authentication to access your application, so that you don’t have to code this support yourself.

Identity protection
Adaptive machine learning algorithms and heuristics can detect anomalies and suspicious incidents that indicate potentially compromised identities. Enterprises can evaluate the detected issues and take appropriate mitigation or remediation actions.

Conditional access
Keep corporate data secure while giving your users an experience that allows them to do their best work from any device. Enterprises can allow or block access or challenge users with multi-factor authentication, device enrolment or password change.
