OneLogin SmartFactor Authentication vs RSA ID Plus: Side-by-Side Comparison (2026)

Short answer

Security teams at startups and mid-market companies should choose OneLogin SmartFactor Authentication if they need MFA that actually adapts to risk instead of demanding the same friction from every user. The AI-driven risk scoring engine adjusts authentication factors dynamically based on login context, SMS, and device behavior, which means legitimate users stay unblocked while suspicious attempts get harder to bypass. Skip this if you're an enterprise with on-premises infrastructure requirements or need passwordless authentication as your primary goal; OneLogin's strength is conditional MFA, not replacing passwords entirely. Mid-market and enterprise teams standardized on Active Directory who need passwordless authentication without ripping out their infrastructure will get the most from RSA ID Plus. The platform handles hybrid and on-premises deployments that competitors often force to the cloud, and its risk-based authentication powered by RSA Risk AI actually adjusts access controls based on behavioral anomalies rather than just layering on another factor. Skip this if you're a pure-cloud shop or need identity verification as a revenue-generating product; RSA ID Plus is built for internal workforce access, not customer-facing identity.
