Lovable.dev Security: Complete Protection Guide

Security in Lovable Applications

While Lovable.dev generates secure code by default, understanding security principles ensures your application stays protected as it grows.

Authentication Security

Protect user accounts with proper authentication:

• Use Supabase Auth: Built-in security features and best practices
• Enforce strong passwords: Minimum length and complexity requirements
• Enable MFA: Two-factor authentication for sensitive applications
• Implement session management: Proper token handling and expiration

Data Protection

Secure your application data:

• Row Level Security: Always enable RLS on Supabase tables
• Input validation: Validate and sanitize all user input
• Encryption: Use HTTPS and encrypt sensitive data at rest
• Access control: Implement proper role-based permissions

API Security

Protect your API endpoints:

• Authenticate all requests
• Rate limit to prevent abuse
• Validate request payloads
• Use CORS properly

Frontend Security

Secure the client-side:

• XSS Prevention: Sanitize user-generated content
• CSRF Protection: Use tokens for state-changing operations
• Secure storage: Never store sensitive data in localStorage
• Content Security Policy: Implement CSP headers

Compliance Considerations

Meet regulatory requirements:

• GDPR: User data rights and consent management
• CCPA: California privacy requirements
• HIPAA: Healthcare data protection (if applicable)
• SOC 2: Security controls for SaaS applications
