An authenticator in cybersecurity is a method used to verify the identity of a user attempting to access a system or service. This can include something the user knows (such as a password or PIN), something they have (such as a security token or smart card), or something they are (biometric data like fingerprints or facial recognition). Authenticators are crucial in ensuring only authorized users can access sensitive information or systems.
