Hey there! Nice to meet you!
Important: If the hacker was able to remove the verification methods (the recovery phone number) from your husband's account, the workarounds below will not work, and the only way to recover your husband's account is through the account recovery webform: https://account.live.com/acsr
Also, if he has an active 2FA, ACSR will inform him that his recovery request will be ignored. If he only receives a message indicating that the recovery request is successful or that insufficient information was provided, this means that 2FA is disabled.
If the recovery phone number is still linked to your husband's account and if he still has access to it, kindly have him perform these steps to fix the verification method error:
- Perform a password reset via Incognito/InPrivate window using different devices and network services.
- If you receive an error message or you can't receive the verification codes from the recovery phone number, wait exactly 48 hours to reset the password.
- If the issue persists, kindly wait exactly 1 week to perform another password reset. The idea is to wait for the account lock to expire first before you reset the password, as stated in this article: https://support.microsoft.com/account-billing/troubleshooting-verification-code-issues-409090c4-92b5-42b9-8ae6-bcc97e62fc48#:~:text=If%20you%20received%20a%20Microsoft%20verification%20code%20that%20you%20did#:~:text=If%20you%20received%20a%20Microsoft%20verification%20code%20that%20you%20did
Important: Please make sure not to attempt to sign in or reset the password within that timeframe (48 hours or 1 week), as this may reset the lock cooldown.
Once he regained access to his account, kindly have him secure his account by enabling the two-step verification feature and ensure that the verification methods are updated on account.microsoft.com > Security > Manage how I sign in
Lastly, I recommend following the guide from this thread to prevent unauthorized logins: https://learn.microsoft.com/answers/questions/4049625/someone-is-repeatedly-trying-to-access-or-hack-my?forum=windows-all&referrer=answers
Thank you for your understanding! Please feel free to let me know if you need anything else.
Best regards,
