## Description

In many WordPress installations is possible enumerate usernames through the author
archives, using urls like this:

http://wpsite/?author=1

http://wpsite/?author=1/

http://wpsite/?bypass=1&author%00=1

http://wpsite/?author%00=%001

http://wpsite/?%61uthor=1

And recently wordpress since 4.7 comes with a rest api integrated that allow list
users:

curl -s http://wpsite/wp-json/wp/v2/users/
 curl -s http://wpsite/?rest_route=/wp/
v2/users curl http://wpsite/?_method=GET -d rest_route=/wp/v2/users

Know the username of a administrator is the half battle, now an attacker only need
guest the password.
 This plugin stop it.

Also, is possible get usernames from the post entries.
 This plugin, hide the name
of the author in a post entry if he is not using a nickname. Also, hide the url 
page link of an administrator author.

The main goal is hide the administrators usernames.
 Obviously, is better not choose“
admin” as the username because is easiliy guessable.
