Two-factor authentication (2FA), also known as multi-factor authentication in broader terms, is a security process that requires users to provide two distinct forms of identification to verify their identity and gain access to resources or credentials. It adds an extra layer of protection beyond traditional username-password combinations. Common methods include one-time passwords (OTP) delivered via SMS, email, or voice calls; hardware tokens; biometric verification (such as fingerprints, iris scans, or facial recognition); public key infrastructure (PKI); and smart cards combined with PINs. By combining something the user knows (e.g., a password), something they have (e.g., a phone or token), or something they are (biometrics), 2FA significantly reduces the risk of unauthorized access from data breaches, phishing, or stolen credentials. It is widely adopted in sectors requiring high security, including banking, healthcare, government, and consumer electronics, ensuring compliance with regulations like PCI DSS, HIPAA, and GDPR.
