Instead of LinOTP

LinOTP alternatives

LinOTP is a free, open-source MFA platform for protecting digital identities and transactions. It supports Android, iOS, Linux, Windows, web, APIs, and self-hosted deployments, with protocols such as SAML, OIDC, ADFS, and RADIUS. Organizations can connect Active Directory, LDAP, and several SQL databases, use app, push, QR, SMS, email, or hardware tokens, and offer offline Windows login and token self-service. Its virtual appliance and Kubernetes container options support distributed installations, while signed audit logs and stated compliance coverage address governance needs.

Readers may still seek alternatives because LinOTP's current download page centers on Debian 10 packages; RPM packages are available only for LinOTP 2, and other distributions may require source or pip installation. LinOTP's software is free, but paid support, subscriptions, SaaS, training, and emergency assistance are separate offerings. Compare deployment control, supported operating systems, authentication methods, integrations, policy features, reporting, and commercial terms. Also check whether you need a focused mobile authenticator, adaptive decisions, broader directory connections, or a vendor-managed cloud service.
