Why should organizations migrate to a multifactor authentication strategy?

While more secure, no authentication method is 'never compromised'; MFA significantly *reduces* the risk but does not eliminate it entirely.

Biometric authentication is a *type* of authentication factor and can be one component of MFA, but it does not *lead* to the need for MFA due to its ability to be compromised; rather, its potential for compromise makes MFA even more desirable.

Multifactor authentication inherently requires *multiple* pieces of evidence (factors) for an authentication attempt, which is its core principle and strength.

Single methods of authentication, such as just a password, are inherently more vulnerable to compromise through techniques like phishing, brute-force attacks, or credential stuffing. Multifactor authentication requires multiple independent pieces of evidence, making it substantially more difficult for an attacker to gain unauthorized access even if one factor is compromised.
