AccessMatrix UAS vs OATH (Open Authentication): Side-by-Side Comparison (2026)

AccessMatrix UAS

Mid-market and enterprise teams standardizing on vendor-agnostic authentication will find AccessMatrix UAS valuable for avoiding lock-in while supporting biometrics, FIDO2, and hardware security modules in parallel. The platform handles 100 million plus user scale and integrates with token vendors from OneSpan to Thales without custom engineering, which matters when you're already managing heterogeneous hardware across regions. Skip this if your organization needs out-of-the-box connectors to your existing identity provider; AccessMatrix is an authentication server, not a replacement for your IAM platform.

OATH (Open Authentication)

Security architects building authentication systems across multiple vendors should adopt OATH standards because they eliminate proprietary lock-in while maintaining interoperability that commercial MFA platforms can't guarantee alone. OATH's RFC-standardized specifications (HOTP, TOTP, OCRA) have been validated across thousands of enterprise deployments and certification profiles ensure your chosen vendors actually implement them consistently. This isn't a replacement for your MFA vendor; it's the foundation layer that keeps your authentication stack portable when your vendor relationship changes or your security requirements tighten.
