The password problem
Weak and reused passwords are the leading cause of data breaches. As developers, we must implement systems that protect users.
Secure storage
Never store passwords in plain text. Use slow hashing algorithms: bcrypt, Argon2, or scrypt. Always add a unique salt per user.
Password policies
Require minimum 8 characters, character type combination, but avoid excessive rules that frustrate users. Prioritize length over complexity.
Multi-factor authentication (MFA)
Implement at least one second factor: TOTP (Google Authenticator), SMS, or FIDO2 security keys.
Password managers
Recommend managers like 1Password, Bitwarden, or Dashlane to your users and team. Essential for maintaining unique, secure passwords.
Rate limiting
Limit login attempts. Implement temporary lockout after failed attempts. Use CAPTCHA as an additional layer.
Conclusion
Password management is a development responsibility. At Vynta we implement robust authentication systems with security best practices.
