DualShield is a unified multi-factor authentication (MFA) platform that supports a wide range of authentication methods across three primary categories: knowledge-based (what you know), token & device-based (what you have), and biometrics (what you are). The platform provides the following authentication methods: - **On-Demand Password**: Passwords delivered on demand to the user. - **One-Time Password (OTP)**: Includes support for OATH-certified hardware tokens (SafeID), mobile authenticator apps (MobileID), and grid cards. - **Push Authentication**: Authentication via push notifications. - **Device Authentication**: Uses device fingerprinting as an authentication factor. - **FIDO Security Keys**: Supports FIDO2 and U2F security keys. - **Security Cards**: Card-based authentication. - **Biometric Authentication**: Supports keystroke recognition, fingerprint recognition, face recognition, and voice recognition. - **Mutual Authentication**: Includes Site Stamp and Two-Way OTP mechanisms to authenticate both the user and the server. - **Challenge & Response**: Authentication via challenge-response protocols. DualShield can be deployed across a range of use cases including MFA for VPN, Remote Desktop (RDP), Windows/macOS/Linux login, Active Directory domain login, Microsoft Entra-joined devices, Exchange email (OWA, Outlook Anywhere, ActiveSync), Office 365, IIS websites, and cloud services. It is also available as a SaaS offering with MFA & SSO Service, Token Management Service, and Token Verification Service.
