Starting this morning, Edge does not remember logins to any website

This didn't work for me. Hosted App Data was not selected anyway.

Was anything selected on that settings page? Which bits, if so?

There is another possible cause for this fault, which may or may not be related to the Hosted app data bug: running a scheduled task using S4U authentication causes saved credentials to go missing or otherwise malfunction¹. 

When you notice that your credentials have gone missing for a website, open a new tab, type or copy edge://histograms/OSCrypt into the address bar and press Enter. Do you see a line referring to OSCrypt.Win.KeyDecryptionError with an error code of -2146893813? If so, Bingo! You've hit the bug.

To find what's causing it, open PowerShell (just use search to find the app), paste this command into the window and press Enter:

Get-ScheduledTask | foreach { If ((xml).GetElementsByTagName("LogonType").'#text' -eq "S4U") { $_.TaskName } }

This will produce a list of scheduled tasks using the authentication method suspected of causing the fault you're seeing. If there are any, they are the culprits. Make a note of them.

Then open Task Scheduler (again, use search to find it) and locate the offenders in the list of tasks displayed. Right-click on the ones you identified and select Disable. Close Task Scheduler and everyting else, then restart the computer. 

It may be wise to wait a few moments for things to settle down, then reopen Task Scheduler again just to check that the tasks you disabled still are disabled - the program or service that created a task may sneakily have re-enabled it.

Go about your normal business to find out whether your login data are now being retained as they should be.

Please post back to tell us what happened.

Local Data Encryption in Chromium – text/plain (textslashplain.com)(Eric is the senior program manager responsible for security on the Edge team.)

PS All of this will be unnecessary once the fix has been developed and deployed, so keep your fingers crossed and Windows and Edge updated.

Win10 2004. Chromium Edge version 86.0.622.43 (official Build) (64-bit).

I set Edge to clear browsing data each time I close the browser. Enabled to clear all data except for "Cookies and other site data" which I left disabled. Yet, every time I go back to a site where I am logged-in, I am logged-out and need to log back in again. I tried disabling other options that could maybe clear persistent cookies, namely "Site permissions", but no change, still keep getting logged out. The only way I can stay logged-in between sessions is to leave all those clear browsing data options disabled. Which is definitely not my preference.

Is this a known issue? The other options in those settings don't appear to have anything to do with cookies but maybe I am missing something?

Any advice would be appreciated.

TIA... Jim

Hi Jim,

Yes, there are reports of the same. There are variations of the errors - where one is browser wide and the other is system-wide.

Hey, everyone! I'm the Community Manager for the Edge team. I wanted to hop in and let y'all know that the team is investigating what's going on here. In the meantime, we suggest that you head to edge://settings/clearBrowsingDataOnClose and ensure that Hosted app data is NOT selected, as a temporary workaround. This should ensure that you stay signed into your websites.

I'll reach out with an update once I hear from the team again. We appreciate your patience while we work on getting this resolved. :3

If it is as it is,

Right-click Start and choose Windows Powershell(admin).

Copy and paste the following:

Get-ScheduledTask | foreach { If ((xml).GetElementsByTagName("LogonType").'#text' -eq "S4U") { $_.TaskName } }

If you get an apps list, you need to disable them in the task scheduler and see if the issue is resolved.

Hey Sumit,

Yep, that's the little devil causing the problem. Enabled everything again except for "Cookies and other site data" and, as per your suggestion, left "Hosted app data" disabled and... voilà, that did the trick. 

Thank you so much for your prompt and very helpful reply.

Cheers... Jim
