Shorter Nonce Lifetime
Makes WordPress security tokens (nonces) expire after 4 hours instead of up to 24, shrinking the window in which a leaked link can be reused.
Snippet Library

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.
