I removed Chrome, IE, Edge and Firefox and reinstalled all. So far, it forgets my passwords for Google, Outlook, Quicken.com, Microsoft.com, and any site that requests the user id and password in two separate steps. I've been working on this for a week and cannot get it resolved. I've tried all of the steps in all of the preceding posts with the exception of rolling back the Windows update.
Firefox was not affected by the update as it is not Chromium based. To get your saved passwords back in Firefox you need to sign into your Firefox account and turn on sync. Once your passwords and sign ins are repopulated you can sign out of your Firefox account and they will stay unlike Chrome and Edge Chromium where you have to stay signed in to your Google account for Chrome and your Microsoft account for Edge chromium to keep them. Once you sign out of those two they will no longer be visible after a restart or wake from sleep. If you are within the 10 day grace period after installing version 2004 you can try rolling back to your previous version. Why Microsoft and Google now made it where you have to sign in to your accounts and turn on sync in order to use your saved sign ins and passwords is beyond me unless they want to track you on the web and see what sites you are accessing and gathering data about you. Like I said I completely uninstalled Chrome and moved Edge off my taskbar as I will not use it anymore unless I absolutely have to. Firefox is my default and I installed Ice Dragon 64 bit which is based on Firefox platform to use as my backup. I hope you have luck as a lot of us are upset over this change.
