HKLM\Software\Policies\Microsoft\Edge
Configure the list of enterprise login URLs (HTTP and HTTPS schemes only) where Microsoft Edge should capture the salted hashes of passwords and use it for password reuse detection. If you enable this policy, the password protection service captures fingerprints of passwords on the defined URLs. If you disable this policy or don't configure it, no password fingerprints are captured. This policy is available only on Windows instances that are joined to a Microsoft Active Directory domain, joined to Microsoft Azure Active Directory, or instances that enrolled for device management. On macOS, this policy is available only on instances that are managed via MDM or joined to a domain via MCX. Example value: https://contoso.com/login.html https://login.contoso.com
