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.
Not all authenticator apps are equal. Compare the best third-party authentication apps of 2026, including Ente Auth, Aegis, Microsoft Authenticator, Zoho OneAuth, and EveryKey, on backup security and encryption.
Identity is the new security perimeter. This guide walks through how IAM works—authentication, authorization, and access control—compares leading platforms, and shows how to fold it all into a Zero Trust strategy.
A one-time password token generates a fresh code for every login, but not all OTPs are equal. Here's how HOTP and TOTP work under the hood, how hardware and software tokens compare, and why passkeys are the next step.
Not all two-factor authentication is created equal. This guide breaks down every 2FA method—from SMS and authenticator apps to hardware security keys and biometrics—and shows which ones actually stop phishing attacks.
Any open switch port is an invitation to attackers. IEEE 802.1X locks those ports down with port-based network access control, authenticating every device before it touches your network.
Basic authentication resends your credentials with every request; form-based authentication swaps them once for a session cookie. That single difference shapes security, MFA support, and logout.
Federated identity attribute mapping decides who gets access to what across SSO. This guide covers SAML assertions, OIDC claims, CEL mapping for Google Cloud, WIF principals, and provisioning.
A one-time password generator turns a shared secret into single-use codes that expire in seconds. This guide covers how TOTP and HOTP work, where OTP breaks under phishing, and how to deploy it securely.
Still relying on text-message codes to secure logins? SMS-based two-factor authentication carries real weaknesses, from SIM-swap fraud to interception. Here's how the attacks work and the stronger options worth adopting.
