What is Two-Factor Authentication (2FA) and Why Is It Important?

Two-Factor Authentication adds an extra layer of security to your Microsoft account by requiring two types of verification before granting access:

  1. Something you know — your password.

  2. Something you have — a second factor such as a code sent to your phone or generated by an authentication app.

Even if someone steals your password, they won’t be able to log in without the second verification factor. This significantly reduces the risk of unauthorized access, identity theft, and data breaches.

By setting up 2FA on your Microsoft account, you protect sensitive information stored in services like Outlook email, OneDrive files, and Office 365 documents.
