HYPR Authenticate vs LinOTP

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.

LinOTP is an open-source platform for multi-factor authentication, aimed at protecting digital identities and transactions. It supports factors including HOTP, TOTP, mOTP, OCRA, SMS and email codes, push, QR, YubiKey, FIDO U2F, WebAuthn, and other hardware tokens. Listed protocols include SAML, OIDC, ADFS, and RADIUS; app integration methods also include HTTP/JSON API, PAM, OpenVPN, SSH, Apache, and WordPress. LinOTP connects to Active Directory, LDAP, and SQL databases including PostgreSQL, MySQL, MariaDB, Oracle, and DB2. A self-service portal lets users register, manage, and reset tokens, while hardware tokens can be resynchronized automatically. The maker describes offline authentication for Windows users without a permanent internet connection. Deployment options include a virtual appliance and containers for Kubernetes and other orchestration platforms. The maker says it can serve small installations through enterprises with thousands of users and distributed setups. The open-source software is listed at free under AGPLv3 and GPLv2; a demo license is also listed at free. LinOTP 3 packages are listed for Debian 10 Buster; RPM packages are currently available only for LinOTP 2.
