Next.js has become a leading framework for building AI applications, but a proper user authentication layer is needed to securely share Next.js-based AI apps within an organization.
Key essentials for organization-scoped authentication include sign-up restriction, role management for multiple concurrent apps, and log collection for data governance.
Four implementation patterns for user authentication in Next.js apps are: Squadbase with invite-only auth, Clerk with rich Next.js UI components, Auth0 for enterprise-grade auth, and IP whitelisting for restricting access by IP range.
Each method has its own features and trade-offs, such as ease of deployment, role management capabilities, integration options, and simplicity of implementation.
