problem to conect xbox live

If you recently turned on two-step verification, you may not know how to sign in to apps or devices that don't accept security codes. Some apps (like the mail apps on some smartphones) and devices (like the Xbox 360) can't prompt you to enter a security proof when you try to sign in. If you get an incorrect-password error with an app or device, you'll need to create a unique app password to sign in. After you sign in with your app password, you're all set to use that app or device. You’ll use this new app password to sign in to your device instead of using your Microsoft account password.

You'll need to create and sign in with an app password once for each app or device that can't prompt you for a security proof.

1. Sign in to your Microsoft account.
2. Under Password and security info, tap or click Edit security info. 
   If you're prompted for a security proof, enter it and tap or click Submit.
3. Under App passwords, tap or click Create a new app password. 
   A new app password is generated and appears on your screen.
4. When you’re prompted for your Microsoft account password on your Xbox console, enter the app password that you created online. 
   After you sign in with your app password, you're all set to use that app or device. You will use this new app password to sign in to your device instead of your Microsoft account password.

Solution 2: Verify your Microsoft Account security information

Follow these steps:

1. Visit Microsoft Account. If you have forgotten your password or it doesn’t work, reset your password.
2. Click Edit security info.
3. Verify your security information. For example, verify the Phone number, Alternative email address and Security question information.
4. Sign out of your Microsoft Account, and then sign in again.
5. Try to sign in to Xbox LIVE again.

Solution 3: Clear the system cache

1. Press the Guide button on your controller.
2. Go to Settings and select System Settings.
3. Select Storage or Memory.
4. Highlight any storage device, and then press Y on your controller. (It doesn't matter which storage device you select; the cache will be cleared for all storage devices.)
5. Select Clear System Cache.
6. When prompted to confirm storage device maintenance, select Yes.

Solution 4: Move and then re-download your Xbox LIVE profile

Note If you want to use a USB memory stick or a USB hard drive to complete these steps, you must format the USB memory stick or USB hard drive for Xbox storage. (See USB memory stick support for Xbox 360.)

1. Move your profile to a USB memory stick or USB hard drive. To do this, follow these steps:
   1. Plug the USB memory stick into your console.
   2. Go to settings and select Storage.
   3. Select All Devices.
   4. Select Profiles and then select your gamer profile.
   5. Select Move.
   6. Select the Memory Unit that you want to move your profile to. 
      Note A Memory Unit can be a USB memory stick, a USB hard drive or the Xbox 360 Hard Drive. Make sure that you move the profile to a USB memory stick or a USB hard drive.
   7. Remove the Memory Unit from your console.
2. Re-download your profile. For information, see Download, move or delete your Xbox LIVE profile.

Solution 5: Reset your Xbox 360 console

To reset your Xbox 360 console, follow these steps:

Solution 6: Delete and then re-download system updates

To delete and then re-download the system updates, follow these steps.

Note These steps delete system updates that are installed on your Xbox console.
