    Sorry to hear that you’re having trouble signing in to Microsoft Defender. Could you please provide a little more information?

    1. Do you currently have an active Microsoft 365 Personal or Microsoft 365 Family subscription?
    2. If so, does that subscription appear when you sign in at account.microsoft.com/services with the same Microsoft account you are trying to use in Defender?
    3. Are you using a personal Microsoft account such as Outlook.com/Hotmail.com, or a work/school account?
    4. Are you able to sign in normally to your Microsoft account through a web browser?
    5. Did Defender work previously on this PC, or is this the first time you are trying to use it?

    Microsoft Defender on Windows needs to be signed in with the personal Microsoft account associated with the Microsoft 365 Personal or Family subscription.
