Security Architecture
This page explains the security architecture used by SecureAuth.
SecureAuth is designed with multiple layers of protection to ensure secure authentication, encrypted data handling, and protected session management.
SecureAuth security architecture focuses on:
- Secure authentication
- Session protection
- Data encryption
- Request validation
- Device monitoring
- Abuse prevention
SecureAuth uses a multi-layered security system.

Protected API AccessSecureAuth uses secure OTP verification for authentication.
Features:
- Expiring OTPs
- Rate-limited requests
- Verification validation
- Replay attack protection
OTP codes are delivered securely through WhatsApp integration.
Benefits:
- Secure delivery channel
- Reduced SMS abuse risks
- Better delivery reliability
SecureAuth uses JWT tokens for authentication.
JWT tokens are used for:
- User authentication
- Session validation
- Protected route access
Security protections include:
- Token validation
- Expiration checks
- Secure signing
- Invalid token rejection
JWT tokens are stored using HTTP-only cookies.
Benefits:
- Prevents JavaScript access
- Reduces XSS risks
- Secure browser storage
Sensitive data is encrypted before storage.
Protected data includes:
- Authenticator secrets
- Backup files
- Sensitive account information
SecureAuth uses AES encryption for secure data protection.
Benefits:
- Strong encryption security
- Secure storage protection
- Data confidentiality
SecureAuth supports secure session tracking.
Features:
- Multi-device sessions
- Session activity monitoring
- Device identification
- Remote session revocation
Every session is validated continuously.
Validation includes:
- Session token checks
- Device verification
- Expiration validation
Authentication endpoints are rate limited.
Protection against:
- Brute force attacks
- OTP spam requests
- API abuse
SecureAuth uses security middleware for additional protection.
Includes:
- Helmet security headers
- Request validation
- Secure headers
Incoming requests are validated before processing.
Validation includes:
- Required field validation
- Authentication checks
- Payload verification
Backup exports are encrypted before generation.
Benefits:
- Secure backup storage
- Protected account recovery
- Safer data migration
SecureAuth supports secure app lock functionality.
Features:
- PIN-based protection
- Secure verification
- Local access protection
For production deployments:
Benefits:
- Encrypted communication
- Prevents traffic interception
- Improves authentication security
SecureAuth helps reduce risks from:
- Brute force attacks
- Session hijacking
- Replay attacks
- Unauthorized access
- XSS attacks
Critical secrets:
- JWT_SECRET
- ENCRYPTION_KEY
- Firebase credentials
- API access tokens
- Use strong random secrets
- Never expose secrets publicly
- Rotate credentials regularly
For maximum protection:
- Use HTTPS only
- Restrict server access
- Enable firewall protection
- Monitor logs regularly
- Rotate secrets periodically
- Revoke suspicious sessions
