Passwords alone aren't enough anymore. Phishing kits and automated password-guessing tools have made stolen credentials common — and once an attacker has your password, that's often all they need to get into your account.
Two-Step Authentication (2FA) adds a second verification step at login, tied to a backup email or an authenticator app. In short: it's an extra code needed to get into your account — easy for you to enter, nearly impossible for a hacker to guess. The numbers make the case:
99.9%
of compromised accounts had no 2FA turned on
— Microsoft
100%
of automated bot logins blocked by 2FA
— Google / NYU / UC San Diego study
$15.6B
lost to account takeover in the US in 2024
— Federal Reserve
$3.05B
lost to business email compromise in 2025 alone
— FBI Internet Crime Complaint Center
Once someone's inside your inbox, they can trigger "forgot password" resets on your bank, request account verification codes, or quietly reroute other accounts tied to that address — and for businesses, it's often how invoices get redirected or staff get impersonated.
A few extra seconds at login is a small price against those numbers.
