What are the different methods of multi-factor authentication?
Multi-factor authentication (MFA) enhances security by requiring two or more verification methods. Common methods include SMS codes, authenticator apps, email links, and biometric verification like fingerprints.
How does an authenticator app work?
Authenticator apps generate time-based one-time passwords (TOTPs) that change every 30 seconds. You link the app to your account by scanning a QR code during setup.
Are there any risks associated with MFA?
While MFA significantly improves security, risks include phishing attacks targeting the second factor and potential vulnerabilities in SMS-based methods.
Which MFA method is the most secure?
Biometric methods, like fingerprint or facial recognition, are generally considered the most secure, followed closely by hardware tokens.
