How do I sign out from the website?
Click on your Display Name in the top right corner, then click on sign out. Make sure you log out of your account if you are using a shared computer. If you used a Microsoft or Facebook account to sign in, you may still need to sign out with them.
If you have forgotten to log out of a device or suspect your account may have been compromised, then you can log out of all devices by clicking on 'logout' and clicking on the 'sign out on all your devices' link.
