Is two-factor authentication enough for online security?

Two-factor authentication (2FA) significantly enhances security, but it's not foolproof. It adds an extra layer, but other factors like password strength and user behavior also matter.

What are the limitations of two-factor authentication?

Some limitations include the risk of SIM swapping, phishing attacks that can intercept 2FA codes, and reliance on the security of the second factor.

What can I do to improve my online security beyond 2FA?

In addition to 2FA, use strong, unique passwords for each account, enable account alerts, and regularly review your account activity.

Are there any alternatives to two-factor authentication?

Yes, alternatives include biometric authentication (like fingerprint or facial recognition), hardware tokens, and password managers that offer secure password generation.

How do I set up two-factor authentication on my accounts?

Most services have a security settings section where you can enable 2FA. You'll typically need to provide a phone number or use an authentication app.
