🛡️ Security Best Practices

🔐 Master Password Guidelines

• Length: Minimum 12 characters (20+ recommended)
• Complexity: Mix of uppercase, lowercase, numbers, symbols
• Uniqueness: Never reuse your master password elsewhere
• Memorability: Use passphrase method for easier recall
• Recovery: Set up secure recovery options

🛡️ Operational Security

✅ Do's:
- Use unique, strong passwords for all accounts
- Enable auto-lock with reasonable timeout
- Regularly backup your encrypted vault
- Keep the application updated
- Use secure password generation
- Monitor for suspicious activity

❌ Don'ts:
- Never share your master password
- Don't use the same password twice
- Don't store passwords in plain text elsewhere
- Don't disable security features
- Don't ignore security warnings
- Don't use weak or common passwords

🔒 Data Protection

• Local Storage: All data remains on your device
• Encryption: Military-grade AES-256 encryption
• Zero Knowledge: Application cannot access your passwords
• Secure Backup: Encrypted backup files only
• Memory Protection: Secure memory handling and cleanup
