Frontegg

Frontegg provides authentication, authorization, and user management services tailored for multi-tenant SaaS products. It handles end-user and admin flows like signup, login, MFA, SSO, roles/permissions, tenant provisioning and exposes SDKs and APIs to embed login experiences or use Frontegg as a standalone IdP.

Key Capabilities

  • Standards-based SSO: Supports OpenID Connect, OAuth 2.0, and SAML 2.0, allowing customers to connect enterprise IdPs such as Okta, Azure AD, or Ping.

  • Multi-tenancy & B2B readiness: Built around tenant isolation, organization-level user roles, and delegated administration—features SaaS vendors typically need for enterprise onboarding.

  • Customizable login & UI: Provides embeddable login widgets, white-label UIs, and React SDKs to tailor the user experience.

  • MFA & passwordless: Supports TOTP, SMS/email codes, and passkey-based (WebAuthn/FIDO2) login options.

  • Role-based access control (RBAC): Built-in role and permission management for tenant-level access segmentation.

Limitations

  • Primarily for SaaS apps: Designed around B2B SaaS multi-tenancy rather than workforce IAM or CIAM for consumer-scale users.

  • Limited governance features: Focuses on access and tenant management; lacks full identity governance (e.g., certification, entitlement review).

  • Vendor-managed dependencies: Frontegg SaaS deployment requires trusting Frontegg for tenant metadata and identity flows unless self-hosted.

  • Protocol depth: While SAML/OIDC support is documented, public details on advanced profiles (e.g., PAR, DPoP, mTLS) are not published.
