What is two-factor authentication and how does it work?
Two-factor authentication (2FA) adds an extra layer of security by requiring two forms of verification before granting access.
What types of second factors can I use for 2FA?
You can use SMS codes, authentication apps, hardware tokens, or biometric verification as second factors.
How does 2FA protect my data from hackers?
2FA makes it harder for hackers to access your accounts, as they would need both your password and the second factor.
Is 2FA foolproof?
While 2FA significantly enhances security, it's not completely foolproof. It's important to use strong passwords and stay vigilant.
