Should you ever lock out your own account and you have SQL access try this
UPDATE users SET login_attempts = 0 WHERE login_attempts > 1 AND user_deleted = 0 AND user_name = '<username>';
Should you ever need to unlock all accounts, not sure why, but you can try this if you have SQL access
UPDATE users SET login_attempts = 0 WHERE login_attempts > 1 AND user_deleted = 0;
