Windows 10: cannot verify server identity message appearing on iphone

eas.outlook.com is mentioned on one error message and outlook.office365.com on latest one

"Windows need to verify your identity" message nearly daily

There's no verification code involved.

• A message appears in the Action Center and says something like "Windows need to verify your identity, click here to continue".
• I click the link and it opens up my user account in System\Accounts\Your email and accounts.
• Under where it says "Manage my Microsoft account", there's a new link that says "Verify".
• I click the Verify link. The cursor spins for about 2 seconds and the Verify link goes away. The end.

 

“We need to verify your identity”,

I have received this code about a 100 times, either to my phone or my e-mail. It lasts about an hour or two, then I get the “We need to verify your identity” pop-up again.

Two-step sign in is not activated.

I also noticed that on the "My devices" page, my desktop PC is shown with detailed info, like motherboard type, Windows 10 Core (10.0.10586.63), etc.

But my other computer, the laptop, is just listed as "PC". No other information is available, not Windows version, no hardware details, nothing. That laptop is the only one that gets this annoying “We need to verify your identity” despite me having entered
the code over a hundred times in any available way.

I am quite certain that the fact that not detailed PC or Windows information is closely related to the “We need to verify your identity” problem.

 

Verify identity message

Microsoft has asked me to Verify my identity. When I answer the question, they say they will send me a code. No code is received. How long does it take for them to send me a code?
