My 5-step security checklist for every new Windows PC is less about paranoia and more about closing the gaps that attackers routinely exploit on fresh installs. A brand-new machine feels secure out of the box, but that impression can be misleading: setup defaults are only the starting point, not...

Windows has a security story that Linux fans often underestimate, and the gap is narrower than the usual platform-war talking points suggest. In three practical areas—full-disk encryption, biometric sign-in, and enforced update hygiene—Windows 11 now offers a more opinionated, more consistent...

Windows Hello PINs are safer than many people assume, but the reason has less to do with the four digits you type and more to do with the cryptography underneath them. Microsoft’s own documentation says a Hello PIN is tied to the device, never sent to the server, and backed by TPM hardware that...

Microsoft’s latest Entra push brings native passkey support to Windows via Windows Hello, while a parallel hardening of Microsoft Authenticator means rooted and jailbroken phones could lose the ability to hold Entra credentials — automatically, and without opt‑out. This is a meaningful step...

Microsoft’s gradual march toward a passwordless enterprise just added a practical new tile: Windows Hello can now act as a passkey authenticator for Microsoft Entra accounts, letting employees use biometric unlock (or PIN) to sign into Entra‑protected resources without typing passwords. This is...

Enable and Use Windows 11/10 Passkeys (Windows Hello) for Passwordless Sign-Ins Difficulty: Intermediate | Time Required: 15 minutes Passkeys are a newer, safer way to sign in to websites and apps without typing passwords. Instead of something you know (a password), you use something you have...

If your fingerprint reader or Windows Hello stopped working after an update, a return to this guide will usually find the problem rooted in a service, policy, driver, or firmware toggle — and nearly every common failure can be fixed without reinstalling Windows. Background: what the Windows...

Microsoft has quietly closed one of the more frustrating security gaps in Windows authentication: starting with the February 10, 2026 cumulative update (OS builds 26200.7840 and 26100.7840), external Windows Hello devices — notably peripheral fingerprint readers and compatible cameras — can now...

I wiped Windows, installed Linux on two Surface devices, and the one thing I miss most is the seamless, built‑in biometric sign‑in—Windows Hello—because Linux today does almost everything else well enough to be a daily driver for an experienced user. rview Linux desktop distributions have...

Microsoft has quietly removed the long‑standing convenience of credential autofill in Windows sign‑in dialogs — a deliberate security hardening shipped in January 2026 that forces organizations to choose between uninterrupted remote support workflows and a stronger defense against a serious...

Microsoft’s preview of Administrator Protection in Windows 11 is a seismic shift in how the platform treats administrator privileges — turning the long‑standing model of always‑on admin accounts into a just‑in‑time, Windows Hello–backed elevation model that isolates elevated sessions, destroys...

Microsoft's January security hardening that silently broke credential autofill has sharpened a long‑needed line in the sand: Windows sign‑in dialogs will now ignore untrusted, injected input — and that breakage, while inconvenient, is an intentional defense against a real Windows Hello...

Microsoft’s January security rollup for Windows quietly removed a long‑used convenience: the ability for some applications and remote tools to autofill credentials into Windows sign‑in dialogs. The change — delivered in the January 13, 2026 cumulative updates (notably KB5074109 and sibling...

Microsoft’s attempt to make privilege elevation in Windows 11 a true security boundary ran into a harsh reality check: decades of legacy kernel behavior are hard to rewrite safely. Google Project Zero’s James Forshaw exposed multiple privilege‑escalation bypasses against the new Administrator...

Microsoft’s terse advisory for CVE-2026-20852 — described as a Windows Hello tampering vulnerability that “allows an unauthorized attacker to perform tampering locally” — should push security teams to treat biometric-signin integrity as a high-priority operational risk, even while authoritative...

Windows Hello promised to make passwords optional by replacing typed secrets with biometrics — a face, an iris, or a fingerprint — and the early demos that paired Windows 10 builds with Intel’s RealSense depth cameras made that promise visible and tangible for everyday users. Background /...

Microsoft’s Security Response Center (MSRC) has recorded CVE-2026-20804: an incorrect privilege assignment in Windows Hello that, according to the vendor summary, “allows an unauthorized attacker to perform tampering locally.” This advisory was published by Microsoft and appears in the vendor’s...

Samsung’s PC browser beta has just taken a meaningful step toward tighter credential protection: the latest Samsung Internet for PC beta (version 29.0.0.148) now requires Windows sign‑in verification before Samsung Pass will reveal saved credentials, forcing local Windows authentication — PIN...

Microsoft’s step to let Windows users save and synchronize passkeys to their Microsoft Account changes the practical calculus for passwordless security: the company has combined Windows Hello’s local biometric and PIN unlock with a cloud-backed passkey vault (Microsoft Password Manager) so users...

Fix Windows 10/11 Sign-In Issues: Reset PIN, Repair Hello, and Regain Access Difficulty: Intermediate | Time Required: 20 minutes Windows 10/11 sign-in problems can show up in frustrating ways: your PIN suddenly “isn’t available,” Windows Hello face/fingerprint stops working, you’re stuck in a...
