ConceptMFA / Multi-Factor Authentication / 二次验证

Multi-Factor Authentication (MFA)

An identity authentication mechanism that adds a second verification factor beyond a password, such as SMS codes, TOTP one-time passwords, or hardware security keys. It significantly reduces the risk of account takeover following credential leakage, but can be bypassed by real-time phishing proxies that hijack session tokens.
