Building Secure User Authentication Systems
Secure authentication is foundational. VibeCode Mentor generates authentication systemswith industry-standard security measures.
Password Security
Never store passwords in plain text. Use bcrypt, Argon2, or PBKDF2 for password hashing. Salt and hash passwords with a strong algorithm.
OAuth2 and JWT
OAuth2 enables secure delegation. JWT tokens are stateless and scalable. Understand when to use each approach.
Multi-Factor Authentication
MFA adds security with second factors like TOTP or SMS. Implement MFA for sensitive applications.
