Authentication

Authentication is the process of verifying the identity of a user or system seeking access to a network or resource. It ensures that only authorized entities gain entry, thus preventing unauthorized access and potential security breaches. This verification typically involves presenting credentials such as passwords, biometric data, or cryptographic keys, which are validated against stored records to confirm their legitimacy. Effective authentication methods, including multi-factor authentication (MFA), enhance security by requiring additional forms of verification beyond passwords alone.

In digital security, authentication plays a critical role in protecting sensitive data and systems from unauthorized access. By implementing robust authentication measures, organizations can safeguard against cyber threats and uphold the integrity of their systems.
