HYPR Authenticate vs OpenOTP Authentication Server

HYPR Authenticate provides passwordless, phishing-resistant multi-factor authentication using passkeys. It turns a smartphone into a FIDO2 credential based on public-key cryptography, eliminating passwords and shared secrets. Users pair phones with computers by scanning a QR code, then approve access with biometrics or a decentralized PIN. Authentication covers desktops, virtual desktop infrastructure, web apps, single sign-on, VPN and RDP; an offline mode supports workstation access without internet connectivity. Multiple phones and computers can be paired, and Remote Lock lets users lock a workstation from a smartphone. Organizations can apply their own branding and connect identity providers such as Entra ID, Okta and Ping, as well as RADIUS infrastructure and SIEM platforms. The service supports iOS, Android, Windows, macOS, Linux and web. Plans include Identity Assurance Access at $3 a month, Identity Assurance Plus at $6 a month and Identity Assurance Advanced at $9 a month, all billed monthly. A free plan, free trial and free pilot for up to 50 users are listed.

OpenOTP Authentication Server is an authentication and identity management solution for multi-factor access, offered for cloud or on-premise deployment. It supports mobile push, smart-card certificates, secure magic links, YubiKey, FIDO2 passkeys and software tokens, alongside factors such as SMS, email, hardware tokens and OATH. Federated access options include SAML, OIDC and OAuth. Directory and identity integrations include Active Directory, LDAP, Entra ID, Okta, Google, Ping Identity and One Identity. The server also provides EAP network access control, mobile electronic signatures and mobile badging. Windows and macOS login plugins are listed, as are PAM plugins for Linux and macOS. OpenOTP is a WebADM sub-package and cannot be installed standalone. Pricing is on request, with a 30-day trial: the cloud trial supports up to 250 OpenOTP users and 50 SpanKey hosts; the on-premise trial supports up to 10 users and includes two active-active HA servers. The Freeware plan costs nothing and includes documentation and forum support only. Enterprise Edition is listed at €1.90 a year, and Enterprise Edition + SLA at €2.28 a year; both prices are shown per user/month based on 250 users and billed annually.
