The Windows build is in review. Leave an address in the form above and you'll get one email on the day it's live. Until then, a Windows user can protect their phone with the same account.

Yes. One account covers your devices, and the plan follows the account rather than the install. Two devices on the free plan, unlimited on a paid one.
