Hideez Blog | Passwordless Authentication News & Tips

A protocol-by-protocol guide for architects deploying single sign-on across hybrid AD environments without ADFS or Entra ID P1/P2. Covers Kerberos, SAML, OIDC, and FIDO2 decision criteria, three deployment architectures, Kerberos hardening recipes, and a compliance map for NIS2, GDPR, and PCI-DSS 8.x. Includes troubleshooting commands and an ADFS migration framework.

Offline MFA enforces a second factor locally on the device — no network, no authentication server, no fallback to cached passwords. This guide compares TOTP and FIDO2 offline authentication methods, maps each to NIS2, DORA, and PCI-DSS 4.0 requirements, and shows how Hideez hardware-bound credentials protect Windows, macOS, and off-domain sessions against stolen-device and pass-the-hash attacks.

NFC FIDO2 security keys deliver phishing-resistant authentication with a single tap, replacing passwords across shared workstations, clinical kiosks, and enterprise IdPs. This guide covers the cryptographic model, threat mitigations, Active Directory and Entra ID deployment steps, compliance mapping to NIS2, HIPAA, and PSD2, and a full TCO breakdown. Includes a buyer's checklist and phased rollout playbook for teams ready to eliminate credential-based risk.
