When requesting a new password from MediaWiki, but failing to enter the correct password, the account will be locked for a day before allowing a request for a new password again. During this period, even administration account can't do anything to unlock the account.
Is there any way to unlock the account right away?

You can run a maintenance script:

Or modify the database:
Alternatively you you can install an extension which allows other administrators to reset your password.
