It includes built-in support for OpenID Connect, SAML, OAuth2, and Webhooks, and ships with pre-configured components for login, signup, user management, and organization hierarchies.

Beyond the initial integration, Frontegg offloads identity maintenance from engineering by enabling non-technical teams to manage identity-related tasks through a secure admin portal. Product, Infosec, and Customer Success teams can enforce security policies, manage users, configure auth flows, and respond to customer needs without dev involvement. Security teams can monitor and enforce identity compliance standards through real-time dashboards and built-in audit trails. Frontegg also ensures continuous updates to identity protocols, so developers don't have to worry about chasing evolving standards. Frontegg reduces developer toil, shortens go-to-market timelines, and keeps engineering focused on high-impact product work.
