I can't login to my microsoft account.

Use Microsoft’s Sign-in Helper with the original email address—not only the phone number—because “username not found” combined with an unfamiliar verification address requires account/alias recovery rather than ordinary Minecraft sign-in.^1^

Recover the account

1. On a device and network previously used for this account, open the official Sign-in Helper:
   https://go.microsoft.com/fwlink/?linkid=2214157
2. Enter the original Microsoft-account email address connected to Minecraft. If available, also try another email alias or Skype name previously attached to the account. Microsoft accounts can have multiple sign-in aliases sharing the same account and purchases.^2^
3. On the verification screen shown in the screenshot, do not send a code to or enter the unfamiliar address. The next action depends on whether the password is known:
   • Password still known: select Use your password. If Microsoft then displays I don’t have any of these, select it and follow the prompts to replace the security information. When all security information is replaced this way, Microsoft requires a 30-day waiting period before sign-in becomes available.^3^
   • Password unknown or rejected: follow the Sign-in Helper into account recovery. If necessary, open the official recovery form directly:
     https://go.microsoft.com/fwlink/?linkid=2214511
4. For the recovery form, use the different working account as the contact address. Supply as much historical information as possible:
   • Old passwords
   • The original email/phone details
   • Xbox gamertag
   • Minecraft or Microsoft purchase information
   • Xbox console hardware ID, if applicable
   • Details matching the period when the account was created
   Complete it, if possible, from a familiar device and location. Microsoft sends the result to the working contact address within 24 hours. If verification fails, the form can be resubmitted up to twice per day.^4^

Important limitation

If you had enabled two-step verification and now cannot access any of its alternate verification methods, Microsoft states that the recovery form and support cannot bypass that protection. Support agents also cannot send password-reset links or access and manually change account details.^4^

Since the earlier support attempt required the inaccessible account, contact support while signed in with the working Microsoft account being used here:

1. Open Contact Microsoft customer support.^5^
2. Choose Personal account.
3. Enter Microsoft account hacked or compromised.
4. Select Get Help, then Contact Support if offered.
5. State that:
   • The original email/phone is no longer recognized.
   • Minecraft displays an unfamiliar verification address.
   • The account owns the Minecraft purchase.

Support can direct the recovery process but cannot manually replace the account’s aliases or security information.

Secure the device and payment methods

Before changing any recovered password, run an updated antivirus full scan. Microsoft recommends scanning first when compromise is suspected.^6^

After recovery:

• Set a new, unique password.
• Remove unknown aliases and verification methods.
• Review recent sign-in activity and select This wasn’t me or Secure your account for activity you do not recognize.^7^
• Review the payment method connected to the account and contact the payment provider immediately if any unauthorized charge appears.
• Do not post the full account address, recovery address, codes, receipts, or payment details publicly.
