How does Okta SSO differ from AWS IAM Identity Center for enterprise SSO?

Okta manages workforce SSO across all clouds and on-premises applications from a single platform, with Universal Directory as the authoritative identity store. IAM Identity Center is primarily designed for AWS multi-account access with limited non-AWS application SSO. Most enterprises use Okta (or Azure AD) as the primary IdP and federate into IAM Identity Center for AWS-specific access, rather than using IAM Identity Center as their enterprise SSO platform.

What is Auth0 and when should I use it instead of AWS for SSO?

Auth0 (now part of Okta) is a developer-first CIAM platform designed for adding authentication to applications via SDKs and APIs. It handles customer-facing SSO with social login, MFA, branding, and extensible login flows via Actions (serverless functions). AWS Cognito is AWS's equivalent for CIAM. Auth0 provides a richer developer experience and more pre-built social connections. Choose Auth0 when building consumer or B2B SaaS applications needing flexible, brandable authentication.

What is Frontegg and how is it different from traditional SSO platforms?

Frontegg is an embedded authentication and user management platform designed for B2B SaaS products. Rather than managing SSO for your employees, Frontegg enables your SaaS product to offer enterprise SSO (SAML, OIDC) to your customers' organizations, with tenant management, role-based access, audit logs, and self-service portals. It's positioned for SaaS builders who need to add enterprise-grade auth to their product without building it from scratch.
