This guide documents the complete implementation of Phase 6 - Authentication & Multi-Tenancy for the DevOps Monitoring Dashboard.

The authentication and multi-tenancy system provides:

• NextAuth.js Integration: Secure authentication with multiple providers
• Role-Based Access Control: Admin, Editor, and Viewer roles
• Multi-User Support: Each user can save their own dashboards and configurations
• User Management: Admin panel for managing users and permissions
• Session Management: Secure session handling with JWT tokens

User → Login Page → NextAuth.js → Database → JWT Token → Protected Routes 

User → User-Specific Config → Multi-Tenant Manager → Isolated Data Storage 

model User {  id String @id @default(cuid())  email String @unique  name String?  image String?  password String? // For credentials authentication  role UserRole @default(VIEWER)  createdAt DateTime @default(now())  updatedAt DateTime @updatedAt    // Relations  accounts Account[]  sessions Session[]  dashboards Dashboard[]  configurations Configuration[]  teams TeamMember[]  createdTeams Team[] }

enum UserRole {  ADMIN // Full system access  EDITOR // Can modify configurations  VIEWER // Read-only access }
