Do You Need the Xbox Live App on Windows Phone? (Platform Dead)

No, and you can't really use it anymore. Windows Phone / Windows 10 Mobile reached **end of life December 2019**. The Xbox Live app was removed from the Store; Microsoft services (auth, notifications) no longer function on the OS.

Access Xbox Live Elsewhere

• Xbox Console (Series X|S, One, 360)
• Windows 10/11 PC – Xbox Game Bar (Win+G), Xbox App
• iOS / Android – Xbox App (chat, remote play, store, achievements)
• Web: account.xbox.com / xbox.com/play (Cloud Gaming)

If you still have a Windows Phone, it's time to migrate—security updates stopped, banking/auth apps fail.
