failed logins with differents users

Hi
I’m testing your plugin on different websites to try to understand how (and why) on the log results I see a lot of failed logins with the different users

For all these websites, the wp-admin folder is protected by htaccess/htpasswd

How is possble the different users names can be seen the log results with these failed logins if htaccess suppose to protect ?

I spent a lot of time online to read websites and forums to read

i added in the root htaccess these lines :

  Require all denied



	order allow,deny
	deny from all

But nothing changes, still failed logins
In another answser you wrote, I see you propose to install Limit login attempts

I dont understand why the htaccess/htpasswd I placed in the wp-admin folder dont block these failed logins

Thanks for your answer and help
