Two-Factor Authentication (2FA) works by adding an additional layer of security to your online accounts. It requires an additional login credential beyond just the username and password to gain account access, and getting that second credential requires access to something that belongs to you.
Can 2FA authenticator be hacked?
Hackers can now bypass two-factor authentication with a new kind of phishing scam. However, security experts have demonstrated an automated phishing attack that can cut through that added layer of security—also called 2FA—potentially tricking unsuspecting users into sharing their private credentials.
