Hey there! Nice to meet you!
There is a possibility that a hacker using a bot is repeatedly attempting 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 or (request an account recovery if you do not have access to the verification methods) using an InPrivate window or Incognito. Also try using different devices and network services.
- Wait 24 hours to perform a password reset/account recovery, but please make sure not to sign in or 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
You may check this link regarding account blocks for reference: 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
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
