You cannot recover a Guest profile. Guest accounts are **temporary, local-only profiles** with **no cloud backup, no persistent ID, and no password**.
| Scenario | Solution |
|---|---|
| Friend used **their own Microsoft Account** on your Xbox | They sign in on *their* console / Xbox app / account.microsoft.com. Their data follows the account, not your console. |
| You created a **Child Account** via Family Settings | It's a full Microsoft Account. Recover at account.microsoft.com/account/recovery. |
| You lost access to **your own Microsoft Account** | Account Recovery Form: Provide old passwords, Xbox serials, purchase history, Skype contacts, billing info. |
| You want **saves from a Guest session** | **Gone.** Guest saves are stored in temporary title storage, wiped on sign-out. No recovery. |
If the person was a friend: Ask them for their Microsoft Account email. They own their data. You only hosted the session.
