Enterprise-Grade Security
Modern Auth implements industry-leading security practices to protect user data and prevent unauthorized access
Password Security
Password security in Modern Auth is implemented using multiple layers of protection to ensure user credentials remain secure even in the event of a data breach.
- Argon2id / bcrypt hashing with optimal work factors
- Multi-factor password strength validation
- Password breach detection against known compromised databases
- Cryptographically secure password reset flow
- Intelligent account lockout with exponential backoff
- Password history tracking to prevent reuse
import bcrypt from 'bcryptjs';
export const hashPassword = async (password: string): Promise<string> => {
const salt = await bcrypt.genSalt(12); // Higher salt rounds = stronger hash
return bcrypt.hash(password, salt);
};
export const verifyPassword = async (password: string, hashedPassword: string): Promise<boolean> => {
return bcrypt.compare(password, hashedPassword);
};
Authentication & Authorization
Modern Auth uses a sophisticated JWT-based authentication system with a seamless integration with NextAuth.js for secure, token-based access control.
- Short-lived, cryptographically signed JWT tokens
- Secure token refresh and rotation mechanisms
- HTTP-only, secure, SameSite cookies for token storage
- Complete session management and revocation
- Role-based permission system with granular access control
- Support for OAuth2 providers (GitHub, Google, etc.)
export const authOptions: NextAuthOptions = {
adapter: MongoDBAdapter(clientPromise),
session: {
strategy: "jwt",
maxAge: 30 * 24 * 60 * 60, // 30 days
},
jwt: {
maxAge: 60 * 60, // 1 hour
},
pages: {
signIn: "/auth/login",
},
providers: [ /* ... */ ],
callbacks: {
/* JWT and session customization */ }
};
Advanced Protection Layers
CSRF Protection
Modern Auth implements advanced Cross-Site Request Forgery protection with unique per-session tokens and strict SameSite cookie policies. All form submissions and API requests are validated against CSRF tokens to prevent malicious attacks.
XSS Prevention
Built-in XSS protections include content security policies, automatic output encoding, and context-specific input sanitization. React's inherent XSS protection adds another layer of defense against injection attacks.
Rate Limiting & Brute Force Protection
Sophisticated rate limiting is implemented on all authentication endpoints with IP-based tracking and exponential backoff. Suspicious activity detection automatically increases security levels when potential attacks are detected.
Data Validation
Every user input is validated through multiple layers using Zod schema validation both client-side and server-side. This type-safe approach ensures input consistency, prevents injection attacks, and guarantees data integrity.
Security Best Practices
Modern Auth implements security best practices at every level of the application stack:
- OWASP Top 10 Compliance - Protection against all common vulnerabilities
- GDPR-Readiness - Built-in features for data minimization and user consent
- Security Headers - Comprehensive HTTP security headers configuration
- Dependency Scanning - Automated vulnerability detection in dependencies
- Audit Logging - Detailed security event logging for forensic analysis
- Secure Defaults - All security features enabled by default with secure configuration
- Principle of Least Privilege - Granular permission system for limited access
Multi-Factor Authentication
Available MFA Methods
- Time-based One-Time Password (TOTP)
- WebAuthn/FIDO2 hardware security keys
- Email verification codes
- SMS verification (optional)
- Recovery codes for backup access
MFA Implementation
Our MFA implementation follows NIST guidelines for secure multi-factor authentication. The system is designed to be both secure and user-friendly, with step-by-step guidance for users setting up additional authentication factors.
Users can manage their MFA settings from their profile, including adding or removing authentication methods and generating new recovery codes.
