Will it be okay to send today's headline verification code to others?

It's okay. It doesn't matter, the verification codes are all disposable. You can change your password if you are not at ease. Generally, the validity time of verification code is only 30 minutes at the longest, and the validity time of verification code on different platforms is different, only a few minutes, so as long as the other party doesn't do anything during this time, there will be no other problems.
