Allow using the deprecated U2F Security Key API (obsolete)
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 98-103, Windows 7 or later

Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 103. This policy is obsolete because it was intended to be a short-term mechanism to give enterprises more time to update their web content that's incompatible with the change to remove the U2F Security Key API. It doesn't work in Microsoft Edge after version 103. If you enable this policy, the deprecated U2F Security Key API can be used and the deprecation reminder prompt shown for U2F API requests is suppressed. If you disable this policy or don't configure it, the U2F Security Key API is disabled by default and can only be used by sites that register for and use the U2FSecurityKeyAPI origin trial, which ended after Microsoft Edge version 103.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: U2fSecurityKeyApiEnabled
Enabled: U2fSecurityKeyApiEnabled = 1
Disabled: U2fSecurityKeyApiEnabled = 0
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
