Auth0 Platform vs Auth0 Single Sign On: Side-by-Side Comparison (2026)

Auth0 Platform

Developer teams building customer-facing applications need Auth0 Platform because it eliminates the authentication infrastructure tax, letting engineers ship passwordless login and adaptive MFA without building IAM from scratch. The platform covers NIST CSF 2.0 PR.AA identity and access control requirements across cloud deployments at scale, and its Organizations feature handles B2B multi-tenancy patterns that otherwise require months of custom work. Skip this if your priority is on-premises federation or you need deep authorization policy engines; Auth0's fine-grained authorization APIs are solid but secondary to its authentication strength.

Auth0 Single Sign On

Teams managing authentication sprawl across 50+ applications will see immediate friction reduction from Auth0 Single Sign On's Universal Login and passwordless workflows, which cut both user friction and phishing surface simultaneously. SOC2 and HIPAA compliance certifications plus native brute force protection and configurable password policies mean security requirements are pre-baked rather than bolted on afterward. Skip this if you need deep device posture checking or conditional access rules that respond to real-time threat signals; Auth0 excels at authentication itself, not the risk-assessment layer that should sit upstream of it.
