We sincerely apologize for any impact this incident has caused to you, your business, and your customers. At Okta, trust and transparency are our top priorities. Outlined below are the facts regarding this incident. Timing: Impact started approximately on October 14, 2025 Impact resolved approximately on October 16, 2025, at 12:18 PM PDT Detection: Customers began reporting authentication failures when using Okta FastPass on Windows devices after installing recent Microsoft security patches. Impact: End users on Windows 11 devices who had recently installed a Microsoft security update (KB5066835) were unable to complete their login when using Okta FastPass with phishing resistance enabled. Root Cause: Microsoft released a security update for Windows 11 that unexpectedly interfered with a local communication method on end-user devices. Okta Verify requires this communication method to perform its FastPass phishing-resistant authentication. This conflict prevented Okta services from validating the authentication attempt, resulting in login failures for affected end users. Remediation Steps: On October 15, 2025, at 4:48 PM PDT, Microsoft resolved the issue and confirmed that end-users would need to reboot their computers to fully apply the fix.
