TL;DR: Better Auth helps teams move fast, but its library-only model leaves SAML SSO, SCIM provisioning, audit logging, and managed infrastructure to the developer, according to WorkOS. As applications mature, authentication becomes a governance problem, not just an implementation choice.
NHIMG editorial — based on content published by WorkOS: Top 5 Better Auth alternatives for secure authentication in 2026
Questions worth separating out
Q: How should teams decide when a library-only auth approach is no longer enough?
A: Teams should move beyond a library-only approach when enterprise customers require SSO, automated provisioning, auditability, or tenant isolation that the application team would otherwise have to build and operate.
Q: Why do SSO and SCIM need to be evaluated separately in enterprise auth planning?
A: SSO and SCIM solve different governance problems.
Q: What breaks when multi-tenancy is added on top of a basic auth library?
A: What breaks is usually the boundary model.
Practitioner guidance
- Map enterprise identity requirements before choosing an auth stack List SSO, SCIM, audit logging, multi-tenancy, and session control as separate requirements, then mark which ones the application team would need to build and operate internally.
- Separate federation from lifecycle automation in your architecture review Require independent sign-off for authentication, provisioning, and evidence logging.
- Design tenant boundaries as identity policy, not application convention Define how invitations, admin roles, and cross-tenant isolation will be enforced under failure conditions.

Enterprise authentication has become a lifecycle governance problem, not a login problem. Better Auth can handle early application authentication, but enterprise requirements quickly expand into provisioning, federation, auditability, and tenant controls. That shift maps directly to lifecycle governance under NIST CSF and NHI governance patterns, because the control surface is now the identity estate around the app, not the login form itself. Practitioners should evaluate auth stacks by what lifecycle work they eliminate, not by developer ergonomics alone.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, exposing a significant developer behaviour gap, according to The State of Secrets in AppSec.
A question worth separating out:
Q: What should IAM teams look for when evaluating authentication platforms for B2B SaaS?
A: IAM teams should look for federation, automated provisioning, audit logs, and tenant isolation as separate capabilities, not as one bundled promise. They should also check whether the platform reduces operational burden or simply relocates it into custom code and engineering maintenance. The best choice is the one that matches the organisation's governance maturity and customer requirements.
