Multi-Factor Authentication (MFA) is a security method that requires users to verify their identity using more than one type of authentication before gaining access to an application, system, or network. Instead of relying only on a password, MFA combines multiple verification factors to confirm a user’s identity. These additional verification steps can include one-time passwords, authentication apps, security tokens, or biometric data such as fingerprints. By requiring multiple forms of identification, MFA significantly reduces the risk of unauthorised access to sensitive systems and data.
Many organizations now adopt MFA-as-a-Service, a cloud-based approach where a provider manages the authentication infrastructure and integrates it into existing applications and systems. This allows companies to strengthen security without maintaining their own authentication platform.
