If you don't have any device that can be updated to iOS 9 or OS X EI Captain, but you still want to enhance the security of your Apple ID account, you can set up two step verification for your Apple ID.
Two-step verification is a security feature for Apple ID that’s designed to prevent anyone else from accessing or using your account, even if they know your password.
It requires you to verify your identity using one of your devices or another approved method before you can:
Sign in to your Apple ID account page
Sign in to iCloud on a new device or at iCloud.com
Sign in to iMessage or FaceTime
If you want to go through setup again or use a different Apple ID, you’ll have to reset your HomePod.
