Multi-Factor Authentication Guide

Beginner7 min read

Add an extra layer of security to protect your accounts from unauthorized access, even if your password is compromised.

What is Multi-Factor Authentication?

Multi-Factor Authentication (MFA) requires two or more verification methods to access your accounts. Even if someone steals your password, they still can't access your account without the additional authentication factor.

MFA reduces account breaches by 99.9%

According to Microsoft, enabling MFA blocks 99.9% of automated attacks on your accounts.

Recommended MFA Methods

Best: Authenticator Apps

Apps like Google Authenticator, Microsoft Authenticator, or Authy generate time-based codes.
