Microsoft Edge Allows for Web Logins without Remembering Passwords
By leveraging Windows Hello hardware, users can now log into websites using things like IR cameras, fingerprint readers, external security keys, and PINs without having to remember your passwords. Microsoft believes that having these additional means of logging in will not only allows users to log into website more easily, they also think this will assist users with security concerns, and that makes sense from the standpoint of things like key loggers (if a user doesn’t type his password into a field then a key logger can’t grab the password). While this may be true, please keep in mind that the bad buys are always on the lookout to crack the latest security ideas. Additionally you should be sure to follow existing best practices when it comes to passwords. This means be sure you have a safe backup of all your passwords, don’t use the same credentials for multiple sites, etc.
To try this you’ll either Windows Insider Preview 17723 or you can wait for Windows 10 version 1809 to be released.
