Why is windows security asking for username and password

Hi,

To isolate the issue, please provide the following information:

• Are you referring to either the Microsoft Security Essentials or the Windows Defender? If not, please specify which Windows security utility is asking for your username and password.
• Does the issue also occur when you try to connect to other Wi-Fi networks?
• What username and password is being asked (e.g. Microsoft Account, etc.)? If it's other than your Microsoft Account, please specify which account.
• What happens when you try to enter your username and password?
• Were there any changes made on your computer prior to the issue?

Regards.
