What We Tested
This report covers the Authentication API - the system that handles:
- User Login - How users sign into the application
- User Logout - How users sign out safely
- Session Refresh - How the system keeps users logged in
- Account Creation - How new accounts are created
- Password Recovery - How users reset forgotten passwords
- User Permissions - How the system checks what users can do
- Multi-Tenant Access - How the system keeps different organizations' data separate
- Role-Based Access - How different user roles (Admin, Safety Officer, etc.) access the system
Detailed Results
1. User Login (15 tests)
Tests how users sign into the system.
| Test | What We Checked | Result |
|---|---|---|
| 1.1 | Valid email and password | ✅ Works |
| 1.2 | Invalid email format | ✅ Rejected |
| 1.3 | Wrong password | ✅ Rejected |
| 1.4 | Non-existent email | ✅ Rejected |
| 1.5 | Empty email | ✅ Rejected |
| 1.6 | Empty password | ✅ Rejected |
| 1.7 | Missing tenant header | ⚠️ Uses default |
| 1.8 | SQL injection attempt | ✅ Blocked |
| 1.9 | Very long email | ✅ Rejected |
| 1.10 | Uppercase email | ✅ Rejected |
| 1.11 | Null values | ✅ Rejected |
| 1.12 | Missing fields | ✅ Rejected |
| 1.13 | Extra fields | ✅ Ignored safely |
| 1.14 | Whitespace in email | ✅ Rejected |
| 1.15 | Thai characters in password | ✅ Rejected |
When no tenant is specified, the system uses the default tenant. This is expected behavior for development but should be monitored in production.
2. User Logout (3 tests)
Tests how users sign out of the system.
| Test | What We Checked | Result |
|---|---|---|
| 2.1 | Logout with valid session | ✅ Works |
| 2.2 | Logout without session | ✅ Works (safe) |
| 2.3 | Logout with invalid session | ✅ Works (safe) |
Logout always succeeds safely, even if the session is already expired.
3. Session Refresh (5 tests)
Tests how the system renews user sessions.
| Test | What We Checked | Result |
|---|---|---|
| 3.1 | Valid refresh token | ✅ Works |
| 3.2 | Missing refresh token | ✅ Rejected |
| 3.3 | Invalid refresh token | ✅ Rejected |
| 3.4 | Empty refresh token | ✅ Rejected |
| 3.5 | Malformed token | ✅ Rejected |
Session refresh correctly validates tokens and rejects invalid ones.
4. Account Creation (12 tests)
Tests how new accounts are registered.
| Test | What We Checked | Result |
|---|---|---|
| 4.1 | Valid new account | ✅ Created |
| 4.2 | Email already registered | ✅ Rejected |
| 4.3 | Invalid email format | ✅ Rejected |
| 4.4 | Empty email | ✅ Rejected |
| 4.5 | Empty first name | ⚠️ Accepted |
| 4.6 | Empty last name | ✅ Rejected |
| 4.7 | Missing tenant header | ✅ Rejected |
| 4.8 | Very long first name | ✅ Rejected |
| 4.9 | Thai characters in name | ✅ Works |
| 4.10 | SQL injection attempt | ✅ Blocked |
| 4.11 | Null values | ✅ Rejected |
| 4.12 | Missing fields | ✅ Rejected |
Empty first name is currently accepted. Consider adding validation if first name is required.
5. Password Recovery (7 tests)
Tests the "Forgot Password" functionality.
| Test | What We Checked | Result |
|---|---|---|
| 5.1 | Valid registered email | ✅ Email sent |
| 5.2 | Non-existent email | ✅ Rejected |
| 5.3 | Invalid email format | ✅ Rejected |
| 5.4 | Empty email | ✅ Rejected |
| 5.5 | Uppercase email | ✅ Rejected |
| 5.6 | Null email | ✅ Rejected |
| 5.7 | Missing email field | ✅ Rejected |
Password recovery correctly identifies registered users and rejects invalid requests.
6. User Permissions (10 tests)
Tests how the system checks user authorization.
| Test | What We Checked | Result |
|---|---|---|
| 6.1 | Valid authorized request | ✅ Works |
| 6.2 | Missing authorization | ✅ Rejected |
| 6.3 | Invalid token | ✅ Rejected |
| 6.4 | Malformed token | ✅ Rejected |
| 6.5 | Non-existent user ID | ✅ Empty result |
| 6.6 | Invalid user ID format | ✅ Rejected |
| 6.7 | Null user ID | ✅ Empty result |
| 6.8 | Missing user ID | ⚠️ Accepted |
| 6.9 | Null user ID value | ✅ Rejected |
| 6.10 | Missing "Bearer" prefix | ✅ Rejected |
Missing user ID returns empty results instead of an error. This is acceptable but could be improved with validation.
7. Multi-Tenant Access (6 tests)
Tests how the system keeps different organizations' data separate.
| Test | What We Checked | Result |
|---|---|---|
| 7.1 | Invalid tenant | ⚠️ Server error |
| 7.2 | Empty tenant header | ⚠️ Uses default |
| 7.3 | Cross-tenant token | ✅ Blocked |
| 7.4 | Whitespace in tenant | ⚠️ Trimmed |
| 7.5 | SQL injection in tenant | ⚠️ Server error |
| 7.6 | Uppercase tenant | ⚠️ Server error |
Invalid tenant names cause server errors (500) instead of proper error messages (400). While security is maintained (access is denied), the error handling could be improved for better user experience.
Cross-tenant access is properly blocked. Users cannot access data from organizations they don't belong to.
8. Role-Based Access (6 tests)
Tests that different user roles can log in correctly.
| Role | Result | |
|---|---|---|
| Administrator | tn@thaiscada.com | ✅ Works |
| Safety Officer | safety-supervisor@outlook.com | ✅ Works |
| Contractor | safety-contractor1-0@outlook.com | ✅ Works |
| Purchasing | safety-purchasing@outlook.com | ✅ Works |
| Work Owner | safety-owner@outlook.com | ✅ Works |
| Workspace Owner | safety-workspace-owner@outlook.com | ✅ Works |
All six user roles can successfully authenticate and receive appropriate permissions.
Key Findings
What Works Well
- Security is strong - Invalid credentials, SQL injection attempts, and cross-tenant access are all properly blocked
- Session management works correctly - Login, logout, and refresh all function as expected
- Input validation is comprehensive - Invalid emails, empty fields, and malformed data are rejected
- All user roles work - Every role type can authenticate successfully
- Thai language support - Thai characters in names are accepted
Areas for Improvement
- Error messages for invalid tenants - Currently returns server error (500) instead of a clear error message (400)
- Empty first name validation - Consider requiring first name for account creation
- Missing user ID handling - Could return an error instead of empty results
Understanding the Results
What the Status Codes Mean
| Code | Meaning | Is This Good? |
|---|---|---|
| 200 | Success | ✅ Yes - Request completed |
| 204 | Success (no content) | ✅ Yes - Action completed |
| 400 | Bad Request | ✅ Yes (for invalid input) |
| 401 | Unauthorized | ✅ Yes (for invalid credentials) |
| 500 | Server Error | ⚠️ Should be avoided |
Key Terms

- Refresh Token - A special token used to get a new login token without re-entering your password
- Tenant - An organization using the system (each tenant's data is kept separate)
- JWT - JSON Web Token, the format used for login tokens
- Authorization Header - Where the login token is sent with each request
