Authentication is the front door of every application and system. Coverage of authentication protocols, MFA and passkey adoption, federated identity, session security, and the architectural decisions that determine whether identity controls hold up against modern attacker techniques.
The CHAP protocol verifies network identities using a challenge-response mechanism that never transmits the password. Still embedded in DSL, VPN, and RADIUS infrastructure, it remains relevant but carries real risks network teams need to understand.
Iris scanner technology explained — how iris recognition systems work, accuracy advantages, healthcare and banking use cases, and biometric identity verification.
OAuth, JWT, MFA, certificate-based auth and more — best practices for securing application authentication in modern web apps and APIs for IT professionals.
OTP tokens explained — how one-time passwords work, hardware token types, TOTP vs HOTP, and why OTP strengthens multi-factor authentication for enterprises.
Certificate-based authentication replaces passwords with cryptographic certificates verified by PKI. This guide covers how CBA works, mutual authentication, certificate lifecycle management, and Microsoft Entra CBA deployment.
Authenticator apps generate time-based codes that protect accounts even when passwords are compromised. This guide compares the best options for individuals and enterprises looking to strengthen two-factor authentication in 2026.
Cryptographic authentication is the backbone of modern digital security, using mathematical proofs rather than shared secrets to verify identity. This guide covers core methods from public-key cryptography and digital certificates to HMAC and challenge-response, and how to implement them correctly.
EveryKey unveiled a new brand identity, a refined access suite, and a completely redesigned website in this special edition of Unlocked. The changes reflect the company's belief that access should feel effortless — and mark a clearer, more visible chapter for the organization.
Traditional authentication stops at the login screen — continuous authentication keeps verifying identity throughout a session using behavioral signals, device context, and risk scoring. Discover how this approach closes the gap that stolen credentials leave wide open.
