Hackers/bots see my username. How to hide it?

I regularly look at “failed login records” through your plugin and see that a number of hackers/bots are trying to login using my username, which is unique and not the default “admin”. I don’t understand how they can see this. I have applied many of the safety features of your plugin. I have changed my login page url. Yet, the bots see my username and that is a concern.

I’ve read that bots use something called user enumeration. I also clicked that option to disable “user enumeration” but that has done nothing.

Is there a security feature that I am missing that will hide this from hackers?

Thanks,
Rob
