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 typically includes something the user knows (password), something the user has (security token or smartphone app), and something the user is (biometric verification). Implementing MFA significantly reduces the risk of unauthorized access, even if passwords are compromised.

Additional Comment:

Always use HTTPS to encrypt data in transit, protecting credentials from interception.
Implement strong password policies, such as minimum length and complexity requirements.
Consider using OAuth or OpenID Connect for secure and standardized authentication processes.
