What the author says it does
Stop User Enumeration is a security plugin designed to detect and prevent hackers scanning your site for user login names.
User Enumeration is a type of attack where nefarious parties can probe your website to discover your login name. This is often a pre-cursor to brute-force password attacks. Stop User Enumeration helps block this initial attack and allows you to log IPs launching these attacks to block further attacks in the future.
Tools like WPSCAN are designed for use by ethical hackers and make efforts to find user login names. Ethical hackers ask permission first, this plugin is designed to reduce the tools when used without permission and when used in conjunction with fail2ban can block those attempts at the firewall.
If you are on a VPS or dedicated server, as the attack IP is logged, you can use (optional additional configuration) fail2ban to block the attack directly at your server’s firewall, a very powerful solution for VPS owners to stop brute force attacks as well as DDoS attacks.
If you don’t have access to install fail2ban ( e.g. on a Shared Host ) you can still use this plugin.
The plugin can stop the user id being leaked by the oEmbed API call.
Since WordPress 4.5 user data can also be obtained by API calls without logging in, this is a WordPress feature, but if you don’t need it to get user data, this
plugin will restrict and log that too.

Questions the author answers
It doesn’t seem to work!
Are you logged in? This plugin won’t do anything for logged in users, it only works when you are logged out. This is the way it is designed. A common mistake is to install the plugin and test it, while still logged in as admin.
My username still seems to be leaked!
Themes and xml feeds will include your user ‘Display Name’. If you do not specify any name details or nick name, the ‘Display Name’ will default to your user login name. Make sure your Display Name is always set NOT to your user name or it will be leaked in multiple places.
Are there any settings?
Yes, but the default ones are fine for most cases
This doesn’t work with PHP 5.6 or 7.1 !
This plugin does not support PHP less than 7.4. You really need to sort out your hosting, running version of software way past its supported end of life is a security risk.
Will it work on Multisite?
Yes
Why don’t I just block with .htaccess
A .htaccess solution is insufficient for several reasons, but most published posts on the subject do not cover POST blocking, REST API blocking and inadvertently block admin users access. And don’t log the IP to a firewall, the major benefit!

Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin. The author takes donations at their donate page.
