Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 93, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Identity and sign-in User Configuration\Administrative Templates\Microsoft Edge\Identity and sign-in Description
Configure this policy to decide whether WAM is used for authentication in Microsoft Edge on Windows 10 RS1 and RS2. If you enable this setting, WAM is used in the authentication flow on Windows 10 RS1 and RS2. If you disable or don't configure this setting, OneAuth libraries are used instead of WAM on Windows 10 RS1 and RS2. If this policy is enabled, then previous sign-in sessions (which used OneAuth by default) can't be used. Sign out of those profiles. This policy will only take effect on Windows 10 RS1 and RS2. On Windows 10 RS3 and above, WAM is used for authentication in Microsoft Edge by default.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: WAMAuthBelowWin10RS3Enabled
Enabled: WAMAuthBelowWin10RS3Enabled = 1
Disabled: WAMAuthBelowWin10RS3Enabled = 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.
