Two Factor Authentication
Popular online services, such as Google, Facebook, Twitter, LinkedIn, Apple and Microsoft, use two factor authentication to add an extra layer of security for account logins. Besides the username and password, or personal identification number (PIN) or pattern, two factor authentication requires a second token, such as a:
- Physical object – credit card, ATM card, phone, or fob
- Biometric scan – fingerprint, palm print, as well as facial or voice recognition
Even with two factor authentication, hackers can still gain access to your online accounts through attacks such as phishing attacks, malware, and social engineering.
