No, you don't need two accounts. A gamertag is tied to a single Xbox Live account. When you recover it on another console, you're simply signing into that same account. Key points: Xbox Live Gold or Game Pass Ultimate is required on each console for online multiplayer (the subscription follows the account, not the hardware). Profile data (saves, achievements, settings) may need to sync or download from the cloud on the new console. You can set one console as your "Home Xbox" to share subscriptions and digital games with other profiles on that box. One account, multiple consoles—just sign in.
