Best use cases for Auth0
- SaaS products needing customer login with flexible auth flows
- Teams that need enterprise SSO readiness for B2B deals
- Multi-tenant apps needing org/tenant separation patterns
- Product teams that want to avoid running identity infrastructure
- Apps that need many identity providers (social + enterprise)
Who should avoid Auth0?
- You want only AWS-native primitives and minimal external dependencies
- You need ultra-low-cost auth at very high MAU scale without tier jumps
- You don’t want vendor-specific extensibility patterns
- Your auth needs are extremely simple and can be handled by Firebase
- You require full control over data residency and custom infra
Upgrade triggers for Auth0
- Growing MAUs and needing predictable cost controls
- Needing enterprise SSO features for customer procurement
- Needing SCIM provisioning and governance for larger tenants
- Needing advanced security policies (risk, anomaly detection, MFA at scale)
- Needing higher support/SLA as auth becomes mission-critical
