WP Users +

Really simple way to find wordpress login usernames so let's keep this short. So for this we are just going to google "/wp-admin" to find some sites that are running wordpress. Just easier to find some that way.

Next we want to open up Kali linux or your choice of OS and run (it's already installed)

wpscan -u www.vulns-web.com

Replace "www.vulns-web.com" with the website you wish to enumerate usernames for.
Using this can give you emails and/or usernames leaked in databases!
