Single Sign-On (SSO) Protocol Support

This question asks whether your software can connect with your customer's existing login system, so their employees don't need separate usernames and passwords just for your application. Think of it like using your Google account to log into other websites - but for enterprise companies. SSO lets users access your application using the same credentials they use for all their other work tools.

Supporting SSO is often a deal-breaker for enterprise sales. Without it, you're asking IT departments to manage yet another set of passwords, increasing their security risk and administrative burden. Companies with SSO see 50% fewer password-related support tickets and significantly reduced risk of credential theft. For many enterprises, lack of SSO support means automatic disqualification from procurement. Implementing SSO can open doors to larger contracts and demonstrate your commitment to enterprise-grade security.

The biggest mistake is claiming SSO support when you only offer basic OAuth for social logins (Google, Facebook). Enterprise SSO requires SAML or similar protocols that integrate with corporate identity providers. Another pitfall is underestimating implementation complexity - proper SSO requires handling edge cases like session management, logout flows, and attribute mapping that can take months to get right if not planned properly.
