How do I change an authorized device?
If you need to change your authorized device, you can first deauthorize the current device and then authorize a new device.
Click the menu button in the upper right corner, and then Logout. Enter your password and click the Deauthorize button to deauthorize the current computer.
You can also go to User Center and click "Authorized Devices" in the menu. Click the "Deauthorize" of a targeted device to deauthorize from authorized devices.
