Previous Question Next Question

To secure user authentication on a web app, implement multi-factor authentication (MFA), use strong password policies, and ensure secure transmission of credentials with HTTPS.

Example Concept: Multi-factor authentication (MFA) enhances security by requiring users to provide two or more verification factors to gain access. This could include something the user knows (password), something the user has (security token), or something the user is (biometric verification). Implementing MFA significantly reduces the risk of unauthorized access.

Additional Comment:

Always use HTTPS to encrypt data in transit, protecting credentials from interception.
Implement rate limiting and account lockout mechanisms to prevent brute-force attacks.
Store passwords securely using strong hashing algorithms like bcrypt.
