HI Gerardo. I'm Greg, 10 years awarded Windows MVP, here to help you.
Security Key is a feature of organizations with servers, which we do not handle here at all. There is more about this here:
https://support.microsoft.com/en-us/account-bil...
https://answers.microsoft.com/en-us/windows/for...
https://docs.microsoft.com/en-us/answers/questi...
For further help please ask your System Administrator or at our sister forums for IT Professionals, Q&A forums here: https://docs.microsoft.com/en-US/answers/index.... as Microsoft Community is strictly an end-consumer forum.
Solutions we give here will conflict with Group Policy which is not used in consumer Windows at all.
There are also equally good (and sometimes busier) IT Pro forums here:

I hope it helps.
