Multi-Factor Authentication

Meaning

Multi-Factor Authentication, in a biological context, refers to a cellular or systemic requirement for two or more independent, distinct signals or conditions to be concurrently present and verified before a specific physiological response or cellular process is initiated. This mechanism ensures that critical biological events proceed only when all necessary prerequisites are met, providing a robust layer of control within complex regulatory networks. It serves as a cellular checkpoint, validating inputs before committing resources or triggering a downstream effect.
