Hi,
I'm Sumit, here to help with your query in the Microsoft Q&A.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
The passwords should not have disappeared. May I know if you had the sync enabled with your Microsoft account?
If so, kindly go to edge://sync-internals page.
Scroll down to the bottom right until the green table appears.
Let me know the value for passwords in the table.
As an additional try to fix the issue, consider downloading Edge Beta from https://aka.ms/EdgeInsider and sign in. Let me know if the passwords appear.
I look forward to your response and am happy to work with you until we find a solution. Please keep me updated.
