I have 2 MC accounts on my PC - both migrated to Microsoft. Whenever I restart the computer I need to login into one account, unlock the `default` keyring and then I can use both accounts.

Restarting the launcher is fine (login is remembered) but restarting the PC prompts you to login into one of the accounts, after you log in you can use the second account too. It remembers the accounts but doesn't remember the login for some reason.
