Multi-Factor Authentication (MFA) is an authentication method which requires more than one form of authentication to verify a user’s identity. It combines two or more independent credentials, which are typically separate physical pieces of evidence, such as a bank card plus a one-time code sent via SMS. It goes one step further than two-factor authentication, which requires a combination of something the user knows (such as a password) and something the user has (such as a security token).
MFA is widely used to protect sensitive data. It is used by companies and organizations to access cloud-hosted applications and websites, as well as for authenticating users to ensure the security of their data stored on the cloud. MFA also adds an additional layer of security to user accounts by preventing fraudsters from easily accessing the user’s account.
MFA is available in a variety of forms, including biometrics, one-time passwords, smartcards, and security tokens. All of these methods are designed to provide better protection for users, making it harder for an unauthorized user to gain access.
MFA is an important security tool for organizations that handle confidential information, such as financial institutions and healthcare-related companies. By requiring additional authentication, it makes it much more difficult for a hacker to gain access.
In summary, Multi-Factor Authentication (MFA) is an authentication method which requires more than one form of authentication to verify a user’s identity. It is widely used to protect sensitive data and is an important security tool for organizations handling confidential information. MFA is available in a variety of forms, including biometrics, one-time passwords, smartcards, and security tokens.
