lost complete access to my email accounts, have no access where the authenticator send the code

Follow the appropriate path based on what is still accessible.

1. If at least one security method still works (phone, backup email, or another sign-in method):
   1. For a personal Microsoft account, go to the Advanced security options page and sign in using the method that still works.
   2. Select Add a new way to sign in or verify and add a new phone number, email, or method for receiving security codes.
   3. After confirming the new method (by entering the code sent to it), expand the old security info entries that can no longer be accessed and select Remove, then confirm.
   4. Do not remove all existing security info at once, or the account may be restricted for 30 days.
2. If all security info is lost but the password is known:
   1. Start signing in to the Microsoft account.
   2. When prompted to Verify your identity, select I don't have any of these.
   3. Follow the instructions to replace the security info.
   4. After replacement, there is a 30‑day wait before normal sign-in is allowed. During this period, if the old security info becomes available again, it can still be used to sign in, but doing so cancels the pending update.
3. If the password is forgotten and all security info is unavailable:
   1. Use the Microsoft account recovery form as described in Help with the Microsoft account recovery form.
   2. Submit the request via the recovery form and wait for the result.
4. For a work or school account (Microsoft Entra / organizational account):
   1. If some security info is still available, sign in to the Advanced security options page for the work or school account and add a new verification method, then remove the inaccessible ones, as above.
   2. If all security info is lost but the password is known, begin sign-in, select I don't have any of these at the verification prompt, and follow the instructions to replace security info, then wait the required 30 days.
   3. If no methods work or sign-in cannot be completed, contact the organization’s Help desk or IT admin and request that they clear or reset the MFA/security info so that registration can be done again.
5. If locked out of an admin account (only global admin) for a Microsoft 365 tenant because of Authenticator:
   1. Contact Microsoft’s global customer service phone support and clearly state that this is a tenant admin MFA reset issue and that this is the only admin account.
   2. Ask to be routed to the Data Protection team so they can verify identity and reset the authentication methods.

Note: Support agents cannot directly send verification codes or bypass security for consumer accounts; the recovery form and security-info replacement flows are the supported paths.
