DPAPI/OSCrypt bug and similar ...
MissyQ Deleted Eric_Lawrence
Any news of fixes for the faults that cause loss of log-in data, e.g. when a scheduled task uses S4U or when Hosted app data is set to clear on close?

Are these two related?
Noel Burgess These two issues are effectively unrelated.
The DPAPI+S4U Issue (https://crbug.com/1069383) causes loss of Edge's encryption key that protects cookies and credentials. This issue will require a monthly update to Windows 10 to fix; we do not have a date for that fix to announce. https://textslashplain.com/2020/09/28/local-data-encryption-in-chromium/
The Hosted App Data Clear-on-Exit-causes-Cookie-loss issue was a bug in our code. As I understand it, it has already been fixed in Canary.

One new red herring data point: a user posted this at Answers, referring to 'missing log-in' sufferers:
I am wondering how many of these folks are using System Mechanic Ultimate Defense from Iolo. I am, but with Private Guardian, which is new, it deletes saved passwords from my pc. Turned off and passwords are not deleted.
Noel Burgess Thanks for reaching out. I asked someone from the team to look into this, and they agreed that those do seem related. I don't have any news to share yet about a fix, but I will let you know if I hear otherwise!
