Definition
Frontegg is a customer identity and access management platform that provides SaaS companies with embeddable user authentication, authorization, and account management features, letting product teams add login, multi-tenant organization structures, role-based permissions, and self-service admin portals without building this infrastructure themselves. It targets business-to-business software vendors that need enterprise-grade identity features, such as single sign-on and fine-grained roles, exposed to their own end customers.
Overview
Building customer-facing identity, especially for B2B software, requires far more than a login form: companies need multi-tenant account structures, role-based permissions that customers can configure themselves, single sign-on for enterprise buyers, audit logs, and self-service admin experiences their own users manage. Building all of this from scratch is a significant, ongoing engineering investment that has little to do with a company's core product. Frontegg was built to let SaaS vendors embed this functionality instead of building it in-house. Frontegg operates as a set of APIs, SDKs, and prebuilt UI components that a product integrates directly into its application. Authentication flows, whether password, social login, or SAML/OIDC single sign-on, are handled by Frontegg's hosted or embedded login experience, while the application queries Frontegg for a user's roles and permissions within their specific tenant or organization. A distinguishing element is Frontegg's self-service admin portal, which end customers' own IT administrators can use to manage their organization's users, roles, and SSO configuration without filing support tickets with the vendor. Frontegg sits in the customer identity and access management category alongside WorkOS, Auth0, and Stytch. Its emphasis on multi-tenant B2B structures and self-service administration for end-customer admins differentiates it from more consumer-oriented identity platforms, and from WorkOS, which focuses more narrowly on enterprise-readiness features like SSO and directory sync as discrete APIs rather than a full embedded UI suite. This consistency also extends to audit logging, where every permission change made through the self-service portal is recorded automatically, giving the vendor's own support and security teams visibility into customer-side administrative actions without needing separate instrumentation. In practice, B2B SaaS companies integrate Frontegg early in their product lifecycle, or migrate to it when enterprise customers begin demanding single sign-on and granular permission controls that homegrown authentication systems were not designed to support. Product and engineering teams use it to accelerate time to market for enterprise-readiness features that would otherwise require months of dedicated development. Adopting Frontegg means coupling core identity infrastructure to a third-party vendor, which introduces migration risk if the company later wants to bring authentication in-house, and requires trusting the vendor's security practices for handling sensitive credential and permission data. Companies with very simple, single-tenant products may find the multi-tenant feature set more than they need, making a lighter authentication service a better fit. Because the underlying tenant and role model is shared across every integration point, a change made in the admin portal, such as adding a new role, is immediately reflected everywhere the application checks a user's permissions, without requiring a separate synchronization step.
