Details:

Password autofill suggestions in Edge are currently based on top-level domain matching, which means the same credentials can be suggested on sites like account.microsoft.com and office.microsoft.com. With this feature, Edge groups related domains together across various desktop and mobile properties called affiliations. When a customer visits a URL, the Edge client will query the affiliations backend to obtain “affiliated groups” for that URL. The process involves sending a hash of the visited URLs to the service, which then returns a list of affiliated URLs and ensures that the relevant credentials will be displayed in the autofill suggestions across affiliated domains. Admins can control access to this feature using the PasswordManagerEnabled policy.
