MFA stands for multi-factor authentication, which is a security method that requires users to provide two or more pieces of evidence to verify their identity before accessing a system. MFA can prevent unauthorized access to the system if a user’s password is compromised, because the attacker would also need to obtain the other factors, such as a one-time code, a biometric scan, or a physical token. MFA can be implemented using various technologies, such as SMS, email, phone call, mobile app, or hardware device. According to Microsoft, adopting MFA can prevent approximately 99.9% of compromised user accounts, significantly bolstering security measures against unauthorized access12. References:
