Enterprise Authentication Platform

Comprehensive, secure, and developer-friendly authentication for modern applications

Enterprise-grade Authentication

Modern Auth provides a battle-tested authentication infrastructure built on industry standards and designed for enterprise applications with stringent security requirements.

  • Advanced JWT implementation with automatic key rotation
  • Argon2id password hashing with adaptive work factors
  • Sophisticated CSRF protection with dual-token pattern
  • Intelligent rate limiting with IP reputation analysis
  • Secure HTTP-only cookies with SameSite and domain controls
  • Session management with device fingerprinting
  • OAuth 2.0 and OpenID Connect provider integrations
  • SSO capabilities with SAML 2.0 support


import { jwtService } from '@modern-auth/core';


const token = await jwtService.createToken({
  subject: user.id,
  audience: 'api:access',
  claims: {
    roles: user.roles,
    permissions: user.permissions,
    deviceId: fingerprint.id
  },
  expiresIn: '4h'
});


try {
  const result = await jwtService.validateToken(token, {
    audience: 'api:access',
    validateFingerprint: true,
    requirePermissions: ['users:read']
  });
  return result.subject;
} catch (error) {
  logger.security.warn('Invalid token', { error, token: tokenMask(token) });
  throw new AuthError('INVALID_TOKEN');
}

Enterprise Identity Management

Modern Auth delivers comprehensive identity and access management for organizations of any size. Our system handles millions of users with enterprise-ready performance and compliance.

  • Advanced user registration with identity verification
  • Role-based access control with fine-grained permissions
  • Multi-factor authentication with multiple methods
  • Enterprise SSO integration capabilities
  • Automated compliance workflows (GDPR, CCPA, HIPAA)
  • Customizable security policies
  • User directory integrations (LDAP, Active Directory)
  • User impersonation with full audit trails


const userSchema = new Schema({
  profile: {
    firstName: { type: String, required: true },
    lastName: { type: String, required: true },
    displayName: String,
    avatarUrl: String,
    locale: { type: String, default: 'en-US' }
  },
  email: {
    address: { type: String, required: true, unique: true },
    verified: { type: Boolean, default: false },
    verificationToken: { type: String, select: false }
  },
  security: {
    password: { type: String, required: true, select: false },
    mfaEnabled: { type: Boolean, default: false },
    mfaMethods: [String],
    passwordHistory: [{ type: String, select: false }],
    lastPasswordChange: Date
  },
  roles: [{ type: String, ref: 'Role' }],
  permissions: [String],
  status: { type: String, enum: ['active', 'suspended', 'locked'], default: 'active' },
  metadata: { type: Map, of: Schema.Types.Mixed }
}, { timestamps: true });

Advanced Theming System

Modern Auth includes a sophisticated theming engine that ensures consistent brand experiences while respecting user preferences and accessibility needs.

  • CSS variable-based theme architecture for maximum flexibility
  • Hydration-safe implementation to eliminate FOUC (flash of unstyled content)
  • Automatic system preference detection with media query subscriptions
  • Persistent theme settings with local storage and server-side preference sync
  • Smooth theme transitions with configurable animation durations
  • WCAG 2.1 AA/AAA compliant color contrast in all themes
  • Support for multiple theme variants beyond just light/dark
  • Theme tokens API for consistent component styling


import { createThemeContext } from '@modern-auth/theme';


const themeConfig = {
  variants: ['light', 'dark', 'highContrast'],
  defaultVariant: 'system',
  transitionDuration: 200,
  tokens: {
    light: {
      colors: {
        primary: '#0070f3',
        background: '#ffffff',
        text: '#111827',
        /* Additional token definitions */
      }
    },
    dark: {
      colors: {
        primary: '#3b82f6',
        background: '#0f172a',
        text: '#f3f4f6',
        /* Additional token definitions */
      }
    },
  }
};


export const { ThemeProvider, useTheme } = createThemeContext(themeConfig);

Elegant Error Handling System

Modern Auth provides a comprehensive error handling system that delivers consistent, user-friendly error responses across your entire application.

  • Centralized error management with consistent formatting
  • Beautiful, theme-aware error pages for common HTTP status codes
  • Detailed developer error information in development mode
  • Structured error logging with context preservation
  • Automatic retry mechanisms for transient failures
  • Rate limiting with user-friendly messaging
  • Internationalized error messages
  • Security-conscious error reporting (no stack traces in production)


import { createErrorHandler } from '@modern-auth/errors';


const errorConfig = {
  types: {
    AUTH: {
      INVALID_CREDENTIALS: {
        code: 'AUTH_001',
        status: 401,
        message: 'Invalid username or password'
      },
      ACCOUNT_LOCKED: {
        code: 'AUTH_002',
        status: 403,
        message: 'Account locked',
        retryAfter: 30
      },
    },
    VALIDATION: {
      REQUIRED_FIELD: {
        code: 'VAL_001',
        status: 400,
        message: 'Required field missing'
      },
    }
  },
  defaultError: {
    code: 'ERR_999',
    status: 500,
    message: 'An unexpected error occurred'
  }
};


export const { AppError, handleError } = createErrorHandler(errorConfig);
