Background for this topic.
Authentication confirms the identity of users or systems before granting access to resources, typically using factors like passwords (knowledge), hardware tokens (possession), or biometrics (inherence). It establishes trust boundaries that prevent unauthorized entities from impersonating legitimate users or devices within networks and applications.
Weak authentication enables attackers to perform account takeover, privilege escalation, or lateral movement by exploiting stolen credentials, phishing, or replay attacks. Deploying multi-factor authentication (MFA) with independent factors significantly reduces these risks. Secure credential storage, regular rotation, and monitoring authentication logs for anomalies are critical defenses to detect and block unauthorized access attempts early in the attack chain.
Proton has launched Proton Authenticator, a free standalone two-factor authentication (2FA) application for Windows, macOS, Linux, Android, and iOS. [...]
Think passkeys make you phishing-proof? Think again. Attackers are using downgrade attacks, device-code phishing, and OAuth tricks to sneak past modern MFA. See how Push Security shuts them down. [...]
