- AI-assisted development promises quick solutions but lacks depth in complex areas like authentication.
- Building a JavaScript app with OIDC authentication using AI revealed gaps in security and compliance.
- Initial AI-generated code lacked password validation, duplicate account prevention, and secure JWT secrets.
- Each fix introduced new questions about security, standards, and best practices.
- AI didn't proactively suggest OIDC compliance features like PKCE flow or token introspection.
- Frontend security issues like XSS and CSRF vulnerabilities were overlooked without specific prompts.
- Testing revealed race conditions, improper error handling, and missing input validation.
- Production-ready authentication requires features like MFA, audit logging, and disaster recovery.
- AI can't replace domain expertise, especially in security-critical components like authentication.
- Solutions like FusionAuth offer comprehensive, secure authentication out of the box.
