2FA (Two-Factor Authentication) is a security mechanism that requires users to provide two different forms of identification before accessing systems, applications, or accounts. Rather than relying solely on passwords, 2FA combines something you know (password) with something you have (mobile device, security token) or something you are (biometric data) to verify identity.
For UK businesses, implementing 2FA dramatically reduces the risk of unauthorised access from compromised passwords, which account for over 80% of data breaches. Even if attackers obtain login credentials through phishing or data leaks, they cannot access protected systems without the second authentication factor, making it an essential control for meeting Cyber Essentials and GDPR requirements.
GoodChoice IT implements 2FA solutions across Microsoft 365, cloud applications, and remote access systems for London and Surrey businesses. Our deployment includes user training, authentication app setup, and backup recovery procedures, ensuring robust access security whilst maintaining user convenience and supporting compliance obligations.
