WorkOS: How SSO works and the fastest way to add it.
My thanks to WorkOS for sponsoring this last week, once again, at DF.
SSO is table stakes for enterprise deals, but building it into your app yourself means writing SAML controllers, parsing XML assertions, and handling IdP-specific quirks for each provider. Learn how SAML flows work, the tradeoffs between building or buying, and best practices for security, routing, and UX.
Or, skip the hassle and add SSO with WorkOS. Read their developer’s guide to learn more — everything from how SSO works to why WorkOS is the fastest way to add it.
