Why Multifactor authentication is require?
When you log in to your online accounts, a procedure known as “authentication,” you are demonstrating to the service that you are indeed the person you claim to be. Historically, this verification has relied on a combination of a username and a password. Regrettably, this method has its drawbacks. Usernames are frequently easily ascertainable, sometimes being as straightforward as your email address. Additionally, due to the challenge of memorising complex passwords, individuals often opt for simpler ones or reuse the same password across multiple websites.
This is why nearly all online services, including banks, social media platforms, shopping websites, and yes, Microsoft 365, have introduced a method to enhance the security of your accounts. It might be referred to as “Two-Step Verification” (2FA) or “Multifactor Authentication” (MFA) but the effective ones are based on the same fundamental principle. When you log in to your account for the first time on a new device or application, such as a web browser, simply providing the username and password is not sufficient. You require a second element—what we term a second “factor”—to establish and confirm your identity.
