Jul 6, 2019 · the "SSO_POP_Device" is normal, if you are using a microsoft account. it is part of the single sign on function so that when you log on to windows with your microsoft account you don't have to log on to onedrive, mail, etc. the username is a device id (numbers and letters), you should also have a "SSO_POP_user" with your microsoft account username.
