Not only is it working fine and dandy, it is also a snap to use. The password manager service would enable one to add as well as remove passwords from the sites that you happen to pay more than just regular visits. You can add an item manually, or to have things dumbed down, so to speak, by allowing Edge to save the password each time you log in to a site for the first time, before you perform an edit or remove the credential from within the manager itself.
We are keeping our fingers crossed that the folks over at Microsoft will synchronize all of the passwords across various iterations of Edge, which would mean you need not have to fret when you are working from your handset, moving on to a laptop, before making another access via the desktop.
