AZ-104: Microsoft Azure Administrator Full Course - What is Multifactor Authentication

The video tutorial explains multifactor authentication, which involves using at least two factors for security. The primary factors are: something you know (e.g., passwords), something you are (e.g., biometrics like fingerprints), and something you have (e.g., RSA tokens or authenticator apps). Additional factors like geographical location are mentioned but are less common. The tutorial emphasizes the importance of integrating these factors to protect applications from unauthorized access, even if credentials are compromised.
