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.
Forms-based authentication and Kerberos solve the same problem in very different ways. This breakdown compares how each handles credentials, encryption, delegation, and daily administration for your environment.
From legacy logins to passwordless FIDO2, authentication protocols shape access decisions across your network. This guide breaks down Kerberos, LDAP, OAuth 2.0, SAML, and RADIUS so you can choose the right one.
Not all hardware keys are equal. This FIDO2 security key comparison breaks down proprietary vs. open-source tokens, USB-A/C and NFC form factors, FIDO certification levels, biometrics, and enterprise deployment at scale.
Forms-based authentication powers over 80% of web logins, but only when built right. This guide covers secure form design, modern password hashing, hardened session cookies, and MFA to keep your login pages safe.
Passwords alone won't stop account takeovers. This guide compares SMS, authenticator apps, hardware keys, and passkeys, then walks through enabling two-factor authentication on Google, Microsoft, and Apple.
API breaches often start with weak authentication. This guide covers modern API authentication best practices—OAuth 2.1, JWTs, mTLS, scopes, and workload identity—to secure your APIs, microservices, and AI agents.
Passwords can't stop modern credential theft alone. This guide explains what multi-factor authentication really means: NIST assurance levels, the five factors, phishing-resistant methods, and how attackers bypass it.
Passwords and SMS codes keep failing against modern phishing. Hardware authentication ties each login to a physical key and cryptography attackers can't replicate remotely — here's how it works and when to deploy it.
One console for every login, device, and door. This guide explains how centralized access control unifies identity and SSO, supports Zero Trust, and cuts the sprawl that slows hybrid enterprises down.
