Frequently asked questions

PortalGuard Desktop supports both Windows and macOS environments. It integrates directly with the operating system’s login process, enabling secure authentication for both domain-joined and standalone machines.

PortalGuard Desktop is designed to support offline login scenarios. When a device is disconnected from the network, users can still authenticate using cached credentials or pre-configured offline MFA methods, such as biometrics or smart cards. This ensures continuous access without compromising security.

Yes. PortalGuard Desktop can enforce multi-factor authentication for:

  • Local logins (e.g. workstation access in the office)
  • Remote logins (e.g. VPN or remote desktop sessions)

Administrators can define policies based on user roles, device types, or network conditions to ensure consistent security across all access points.

PortalGuard Desktop includes self-service password reset (SSPR) directly at the login screen. This allows users to:

  • Reset forgotten passwords
  • Unlock their accounts
  • Recover access without contacting the help desk

These features reduce IT support costs and improve user productivity.

PortalGuard Desktop can be deployed using standard enterprise tools such as Microsoft Endpoint Configuration Manager (SCCM), Group Policy, or custom scripts. Centralized management allows IT teams to:

  • Configure authentication policies
  • Push updates and patches
  • Monitor login activity and generate reports
  • Manage user enrollment and recovery options

This ensures scalable, consistent deployment across large and distributed environments.
