Microsoft Edge
Enable Application Bound Encryption
Supported on Microsoft Edge version 127, Windows 7 or later
What it does
Enabling this policy or leaving it unset binds the encryption keys used for local data storage to Microsoft Edge whenever possible. Disabling this policy has a detrimental effect on Microsoft Edge's security because unknown and potentially hostile apps can retrieve the encryption keys used to secure data. Only turn off this policy if there are compatibility issues, such as scenarios where other applications need legitimate access to Microsoft Edge's data. Encrypted user data is expected to be fully portable between different computers or the integrity and location of Microsoft Edge's executable files isn’t consistent.

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
