Microsoft today announced a new preview build of Edge browser for iOS devices. This v42.11.0 build comes with new improvements.
Previously, Microsoft only allowed you to delete saved passwords from Edge for iOS. With this update, you can now view the saved username and password of all the websites. You can also easily copy the saved username and password in a single tap.
Another update in this build is related to cookies management. Previously, you were only allowed to enable or disable cookies. In this update, you now have three options: Always block, Allow from websites I visit and Always Allow.
You can access the above improvements from Settings->Privacy menu. If you are an Edge Insider, download the latest build from Test Flight.
