What is Authentication and why do you need MFA?
Authentication is the process of verifying your identity when you sign in to an online service or application. Usually, you need to provide a username and a password to authenticate yourself, but that is not very secure. Anyone who knows or guesses your credentials can access your account and misuse your data.
That’s why you need to add more factors of authentication to protect your account. A factor can be something you know (like a password or a PIN), something you have (like a smartphone or a security key), or something you are (like a fingerprint or a face scan).
MFA stands for multi-factor authentication, which means using two or more factors to verify your identity. For example, you may need to enter a password and a code that is sent to your phone, or scan your fingerprint and use a security key.
2FA stands for two-factor authentication, which is a type of MFA that uses only two factors to verify your identity. For example, you may need to enter a password and a code that is generated by an app, or scan your face and use a push notification.
MFA and 2FA are both ways to improve your security and prevent hackers from breaking into your account. They also help you avoid phishing attacks, which are attempts to trick you into revealing your credentials or personal information.
You should enable MFA or 2FA for your accounts whenever possible, especially for those that handle sensitive or confidential data. You can use various tools and apps to generate or receive your second factor, such as the free Microsoft Authenticator app.
