Unable to recover my Microsoft account after an unrecognized Passkey registration – Minecraft access affected

Hello,

I need assistance recovering my Microsoft account, which I have used for more than 15 years.

Recently, I received a security notification about a Passkey registration that I did not recognize or authorize.

After this incident, I lost access to my account. When I try to sign in or use the recovery process, the system indicates that my original email address does not exist.

I have already tried the official Microsoft account recovery process several times without success.

This issue also affects my Minecraft account. I purchased Minecraft in 2021 through PayPal, and I still have proof of purchase.

I would like to know:

Can Microsoft investigate an unrecognized Passkey registration?

Is it possible that my account security information was changed without my authorization?

Why is my original email address no longer recognized?

Can the Microsoft Account Security team investigate the account's history?

Is there a way to recover my Minecraft purchase and account access?

How can I securely provide proof of account ownership?

I am not asking Microsoft to bypass its security procedures. I am requesting a proper investigation and assistance from a specialist who can help me understand what happened.

Thank you for your assistance.

    Contact Microsoft Support from a different working Microsoft account and report an account takeover in which the sign-in alias may have been replaced, requesting an account-takeover review and providing evidence only through the private support session.^1^

    1. Open an account-takeover support case

    Since the recovery form has already failed several times, do not simply repeat it with the same information.

    1. On Windows, open Start → Get Help. Alternatively, use Microsoft’s public support page.
    2. Enter:
      “Personal Microsoft account takeover — unrecognized passkey added, original username no longer recognized, Minecraft purchase affected.”
    3. Select Contact Support, choose the affected Microsoft account/account-security product category, and then select an available contact method such as browser chat or callback. Contact options depend on product, scenario, operating hours, and subscription.^2^
    4. If sign-in is required, use another working Microsoft account. Make clear that it is only the contact account—not the compromised account.
    5. Ask the agent to:
      • Record this as a suspected account takeover, not a forgotten-password case.
      • Note that the original username now returns “account doesn’t exist.”
      • Check whether the case qualifies for an account-takeover review.
      • Give you a case number and identify the approved private channel for submitting ownership evidence.

    Microsoft’s guidance specifically says to contact support when a previously valid username still produces “We couldn’t find an account with that username.”^3^

    Support agents cannot manually change account details or send a password-reset link. Any restoration remains subject to Microsoft’s ownership-verification process.^4^

    2. Keep the evidence tracks separate

    Prepare a concise timeline and separate the evidence into these categories:

    Security incident

    • Original sign-in address and any former aliases
    • Date/time of the unrecognized passkey notification
    • The original notification, including its full sender and timestamp
    • Approximate date of the last successful sign-in
    • Devices and usual locations previously used
    • Any unfamiliar address shown during a passkey or sign-in attempt
    • Existing Microsoft support case numbers

    A passkey notification confirms that a registration event was reported; it does not by itself establish that the primary alias was changed. However, aliases are sign-in addresses, and removing or replacing one can cause the old address to stop identifying the account.^5^

    Ownership verification

    • Previous passwords
    • Name and birth information originally registered
    • Xbox gamertag or Skype ID, if used
    • Frequently used devices or Xbox console hardware ID
    • Historical billing details
    • Exact Outlook subject lines or contacts, if applicable

    Microsoft recommends completing recovery from a previously used device and normal location and supplying as much historical service information as possible.^6^

    Minecraft purchase

    • PayPal transaction ID and transaction date
    • Minecraft/Microsoft order number
    • Purchase confirmation
    • Edition and approximate purchase date
    • Associated gamertag or Minecraft profile name

    Do not post receipts, order numbers, unfamiliar aliases, passwords, recovery codes, or PayPal details in this public forum. Submit them only through the private case channel.

    3. Treat Minecraft recovery as a linked but separate case

    Minecraft access uses the associated Microsoft account, so restoring that Microsoft account is the primary recovery path. If account recovery cannot restore access, open a Minecraft Support case and provide the Microsoft case number plus proof of purchase for an entitlement review.^7^

    The available guidance does not establish that Minecraft ownership can be transferred from an inaccessible Microsoft account to a new account. Ask Minecraft Support specifically whether any entitlement remedy is available; proof of purchase supports review but does not guarantee a transfer.

    4. Secure unaffected accounts and devices

    Before changing passwords elsewhere, run Windows Security → Virus & threat protection → Scan options → Full scan → Scan now. Microsoft recommends a full malware scan before changing credentials after a suspected compromise.^8^

    Also change the password and enable two-step verification on:

    • The original email mailbox
    • PayPal
    • Any account that reused the same password

    If access is restored, immediately review recent activity, aliases, security information, passkeys, forwarding rules, and connected accounts.
