A broad term for the techniques and methods used to verify a user's identity before granting access to a computer system or network. Classified into three types—possession-based (e.g., IC cards), biometric (e.g., fingerprints, iris scans), and knowledge-based (e.g., IDs and passwords)—these methods can be combined in multi-factor authentication to significantly strengthen security.
