Authentication 1 story

Authentication is the process of proving that a user, device or service is allowed to claim an identity. This category examines passwords, passkeys, multi-factor methods, biometrics, tokens, sessions, credential management and the protocols behind secure sign-in. It is narrower than Cybersecurity because it concentrates on identity verification rather than the full range of threats and defenses. Readers get practical help choosing authentication methods, understanding failure points and improving account access without confusing identity proof with broader authorization.
