Disable XML-RPC
Turns off the XML-RPC interface (xmlrpc.php), a common target for brute-force and pingback abuse. Use it when no app or service needs XML-RPC.

Security snippets for WordPress
Snippets that harden WordPress: turn off XML-RPC, hide the version number, stop user enumeration, add security headers and block risky uploads. Small, reviewable changes for site owners who want fewer attack points without a heavy security plugin.
Accept Application Passwords Only From Trusted IP Addresses
Rejects REST API and XML-RPC logins made with application passwords unless they come from the IP addresses or networks you list, such as your office, CI server or integration partner.
Allow XML-RPC Only From Trusted IP Addresses
Keeps XML-RPC available for the services you list (such as Jetpack or a publishing app on your office network) while answering every other XML-RPC request with a 403 error.
Disable XML-RPC Multicall
Removes the XML-RPC system.multicall method, which attackers use to try hundreds of passwords in a single request, while XML-RPC keeps working for apps and Jetpack.
Emergency Lockdown Switch
Adds a "Lockdown" toggle to the admin bar for administrators. While it is on, only administrators can log in, everyone else is logged out, registration and comments are closed and XML-RPC is off.
