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 explained — how web login forms handle credentials, common vulnerabilities, and best practices for session management security.
Electronic authentication explained — MFA, biometrics, digital certificates, electronic signatures, and how modern methods secure digital identity and access.
Google Authenticator, Microsoft Authenticator, and more — how authenticator apps use MFA to protect accounts even when passwords fail.
Two-factor verification explained — authentication factors, authenticator apps, MFA, and push notifications that protect accounts from credential theft.
Device authentication — biometrics, certificates, MFA, and device fingerprinting — how organizations verify devices and prevent unauthorized access.
PAP and CHAP authentication protocols explained — how legacy password authentication paved the way for modern MFA and secure identity verification systems.
Passwordless, biometric, and adaptive authentication are replacing static passwords — how modern methods are overhauling digital identity security.
Two-factor authentication explained — authenticator apps, hardware tokens, OTPs, and why 2FA is essential for protecting accounts from modern attacks.
Authentication factors explained — how MFA, hardware tokens, authenticator apps, and passwordless methods add layers of protection against credential-based attacks.
