Unprompted Microsoft verification text

Hi,

Thank you for posting your query in Microsoft Community.

I understand your concern and will assist you to resolve this issue.

• 
  Have you enabled two step verification?
  
• 
  Did you make any changes prior to this issue?
  

If you have enabled two step verification in the Microsoft account. You’ll get a security code to your email, phone, or authenticator app every time you sign in on a device that isn't trusted.

Refer the link below for more information.

Two-Step Verification notifications no longer work after using code

I had to log into my MS account one time without my two-factor device being online, so used the "I have a code" method (which, incidentally, takes more steps than it should). Now every MS login defaults to the code method, and when I click "Send an identity verification request to my Microsoft Authenticator app", it never sends the request. How do I re-enable the automatic Approve/Deny two-factor verification notifications?

Hi Debbie,

It is possible that your son is unable to open his laptop while updating due to a corrupted or incomplete installation. To assist you better, we'd like to gather more information:

• Is your son, getting an error message when he tried to turn on his laptop?
• When he tried to open his laptop, are you able to check if the power light stays on?
