About this tag
The credential UI tag covers Microsoft's January 2026 security hardening that blocks autofill and remote input injection into Windows sign-in dialogs. This change, linked to CVE-2026-20804 and CVE-2026-20824, prevents credential prompts from accepting input from untrusted sources like screen-sharing tools, virtual keyboards, and scripted autofill flows. Only trusted local input—such as physical keyboards or properly signed UIAccess assistive applications—is now allowed. The update, delivered via cumulative updates like KB5074109, forces organizations to adapt remote support workflows while strengthening defenses against Windows Hello tampering vulnerabilities. Discussions focus on the security rationale, enterprise impact, and workarounds for helpdesk teams.
