A security process that requires users to provide two or more verification factors to gain access to a resource.
Description
Multi-Factor Authentication (MFA) is an essential security measure in the cybersecurity industry designed to enhance the protection of sensitive information and systems. It works by requiring users to present two or more independent credentials for verification, which can include something they know (like a password), something they have (like a smartphone or security token), and something they are (like a fingerprint or facial recognition). This layered approach makes it significantly harder for unauthorized individuals to gain access, even if they manage to steal a password. Real-world applications of MFA can be seen in online banking, where banks require users to enter a password and then confirm their identity through a text message code. Similarly, popular platforms like Google and Microsoft offer MFA options to protect accounts from hacking. Implementing MFA not only helps secure individual accounts but also protects organizations from data breaches and cyber threats, making it a critical component of modern cybersecurity strategies.
Examples
- Online banking services often require users to enter a password and a one-time code sent to their mobile device.
- Social media platforms like Facebook enable users to activate MFA, requiring a password and a verification through an app like Google Authenticator.
Additional Information
- MFA significantly reduces the risk of unauthorized access to sensitive information.
- Many cybersecurity frameworks and regulations recommend or mandate the use of MFA to comply with security standards.
