Hey there! Nice to meet you!
There is a possibility that a hacker using a bot 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 temporarily blocked.
If the account is still blocked, please perform these steps to resolve an account block:
- Perform a password reset using an InPrivate window or Incognito. Also, try using different devices and network services.
- Wait 24 hours to perform a password reset, but please make sure not to reset the password within that timeframe, as this may reset the lock cooldown.
- If it doesn't work after 24 hours, try waiting exactly 48 hours before resetting the password.
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,
Darhyl
