Set Up Microsoft Authenticator

Overview

The Microsoft Authenticator app is essential after enabling Multi-Factor Authentication (MFA) because it adds a second layer of security to your account, protecting it even if your password is compromised. Instead of relying on less secure methods like SMS codes, the app provides fast and reliable sign-ins through push notifications or time-based codes. It ensures that only you can access your account by requiring something you know (your password) and something you have (your phone). Plus, it supports backup and easy recovery if you switch devices, making it both secure and convenient.
