Duo Multi-Factor Authentication
Zero-trust access security
Enable MFACisco Duo Multi-Factor Authentication adds a critical security layer by verifying user identity through a second factor before granting access to applications, VPNs, and cloud services. Even if passwords are compromised through phishing or data breaches, MFA prevents unauthorized access by requiring something the user has, like their smartphone, in addition to what they know.
Duo supports multiple authentication methods including push notifications to the Duo Mobile app, SMS passcodes, phone callbacks, hardware tokens, and biometric verification. The adaptive authentication engine evaluates risk factors like device health, location, and access patterns to make intelligent access decisions, challenging users only when risk is elevated.
Integration with hundreds of applications is straightforward using SAML, RADIUS, LDAP, and native integrations for Microsoft 365, Google Workspace, Salesforce, VPN appliances, and more. The Duo admin dashboard provides visibility into authentication activity, device health status, and policy compliance across the organization.
