# Authentication System Update - Complete ✅
|
|
|
|
## What Was Done
|
|
|
|
### 1. Database Schema Updates
|
|
Added password fields to:
|
|
- ✅ `ShiftManager` model - Added `password` field (optional String)
|
|
- ✅ `Worker` model - Added `password` field (optional String)
|
|
|
|
### 2. Authentication Logic Updates
|
|
Updated `lib/auth.ts` to:
|
|
- ✅ Check for password field existence
|
|
- ✅ Validate passwords using bcrypt for shift managers
|
|
- ✅ Validate passwords using bcrypt for operators/workers
|
|
- ✅ Return null if password is missing or invalid
|
|
|
|
### 3. Seed Data Updates
|
|
Updated `prisma/seed.ts` to:
|
|
- ✅ Create default hashed password: `muller123`
|
|
- ✅ Apply password to all 4 shift managers
|
|
- ✅ Apply password to all 36 workers (28 operators + 4 Level 2 + 4 engineers)
|
|
- ✅ Maintain existing admin password: `admin123`
|
|
|
|
### 4. Database Migration
|
|
- ✅ Pushed schema changes to PostgreSQL
|
|
- ✅ Re-seeded database with password data
|
|
- ✅ Verified all users have passwords
|
|
|
|
### 5. Documentation Updates
|
|
Updated `CREDENTIALS.md` to:
|
|
- ✅ Add default password information
|
|

|
|

## Current Authentication System
|
|
|
|
### Password Summary
|
|
| User Type | Password |
|
|
|-----------|----------|
|
|
| Admin | `admin123` |
|
|
| All Shift Managers | `muller123` |
|
|
| All Workers/Operators | `muller123` |
|
|
|
|
### Authentication Flow
|
|
1. User selects role (Admin/Shift Manager/Operator)
|
|
2. User enters email and password
|
|
3. System validates credentials:
|
|
- For Admin: Checks `Admin` table, validates bcrypt password
|
|
- For Shift Manager: Checks `ShiftManager` table, validates bcrypt password
|
|
- For Operator: Checks `Worker` table (jobPosition = "Blow Moulder Level 1"), validates bcrypt password
|
|
4. On success: Creates session and redirects to role-specific dashboard
|
|
5. On failure: Shows "Invalid credentials" error
|
|
