Daily Term: Authentication

Authentication

Authentication is the process of verifying the identity of a user or system, ensuring they are who they claim to be. Common methods include passwords, multi-factor authentication (MFA), or biometrics. For example, logging into an email account with a password and a one-time code sent to your phone uses authentication. It’s a critical security step to prevent unauthorized access but can be vulnerable to attacks like phishing if not implemented securely.
