Duo Mobile vs Spriv Adaptive MFA

Duo Mobile provides two-factor and multi-factor authentication for company and personal data on iOS and Android phones and tablets. Users can approve or deny sign-ins with Duo Push, or enter time-based passcodes generated by the app. It also supports third-party TOTP accounts, biometrics, and passcodes. Duo Restore backs up and restores Duo-protected accounts when a user changes devices, and Security Checkup provides a mobile-device security score through app notifications. For organizations, Duo connects with legacy infrastructure, custom apps, VPNs, SaaS tools, and offline devices. Integration methods include RADIUS, SAML/OIDC, Duo Authentication Proxy, and direct API connections. Adaptive policies can consider user role, location, application, network, and device health. Duo says it keeps private keys on users’ devices in a tamper-proof secure element and does not store passwords. The free plan covers 10 users; paid plans start at $3.00 per month, and a 30-day trial is listed. End users needing enrollment or troubleshooting help are directed to their organization’s Duo administrator.

Spriv Adaptive MFA adds multi-factor checks to logins across web, Windows, Linux and mobile environments. Its adaptive authentication can pair a workstation with an environmental identifier from a phone after the user approves a login, then authenticate later matching logins in the background. Other factors include one-way and two-way SMS, TOTP, and Allow/Deny prompts. Windows Remote Desktop logins can use a credential provider, while a PAM module covers SSH, su and sudo on Linux and Unix. Developers can connect their own applications through a REST API with sample code in five languages. Schema and directory needs vary by plan: Business includes Active Directory synchronisation and bulk user import. Large institutions can host custom servers in their own data center; other customers use shared cloud servers. Spriv states that its MFA meets FFIEC, PCI, HIPAA and SOX requirements and does not transfer personally identifiable information. It offers iOS and Android apps, a free plan for up to two users and two servers, and paid service from $7/user/mo. SMS on the free account is billed at carrier cost.
