Hey there! Nice to meet you!
There is a possibility that a hacker repeatedly tried to sign in to your account, which triggered the system to detect multiple failed sign-in attempts or an unusual login pattern and resulted in the account being blocked, forcing you to reset the password to unblock it.
If the account is still blocked, please perform these steps to resolve an account block:
- Perform a password reset via Incognito/InPrivate window using different devices and network services.
- If it doesn't work, 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 you have regained access to your account, kindly secure your account by enabling the two-step verification feature and ensure that your 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,
