It is important from a security point of view that you verify your identity on your Windows 10 PC. Verifying your identity helps you protect your data. If when accessing sensitive information from this device, if Microsoft suspects fraudulent activity, they will ask you to enter a security code which will be sent to your Microsoft Account email ID or your mobile phone number. If you use this device frequently to access important data, then verifying your identity once will help Microsoft that it is indeed you, who is using the PC.
