Why is my sync account being logged out automatically every day?

Being automatically logged out in Edge with my private sync / Microsoft account happens on the up-to-date version of Windows 11 Pro with the normal current version of Edge. I have only a single Edge profile which is private and neither Windows nor Edge is managed by a corporation. However, I edited some policies. So, it may appear to Windows or Edge that there is corporate management. "Passwordless account" and "Two-step verification" are both switched off.
I do have another corporate account to access M365 which is MFA protected (Microsoft authenticator). Also there I am automatically been logged out on a daily basis. 
Can I change the behaviour?
