Multi-factor Authentication (MFA) provides an additional layer of defense by requiring users to provide additional evidence to verify their identity. Benefits of MFA are invaluable.

MFA adds an additional layer of protection beyond username and password (something you know). It helps prevent unauthorised access if a password is compromised or stolen. Attackers would need additional factors, such as a physical token or a unique code sent to a mobile device (something you have) to gain access.

Passwords have always been a problem, and are vulnerable to different attacks, including brute-force attacks, phishing, or password reuse. MFA helps mitigate these vulnerabilities because an additional factor is required, and the attacker would often need both factors to be successful.

MFA can (and should) be implemented across all platforms and technologies in a business, especially any internet facing online services and solutions.

The MFA solution providers offer simpler push notifications to second factor devices. These methods are often a more convenient and efficient user experience for a broad range of users requiring less support issues.

Multi-factor authentication as a control helps to acquire and maintain security compliance against various industry standards and regulations.

User organisation and management is much more simple to manage, where groups or individuals can be assigned access to a solution or service within an organisation, denying access to anyone else.

Multi-factor authentication as a security control is perhaps one of the best investments an organisation can make, mitigating a number of risks.  Providing it is implemented across all technologies of value to the organisation.
