Question

Explain line-by-line what the following snippet code from a .htaccess (WordPress) file means:

order allow,deny
deny from all
satisfy all

Answer 1

Order allow, deny tells your web server that the Allow rules are processed before the Deny rules. If the client does not match the Allow rule or it does match theDeny rule, then the client will be denied access.

deny from all is used to restrict visit access to certain IPs.

Satisfy directive is only useful if access to a particular area is being restricted by both username/password and client host address. In this case the default behavior (satisfy all) is to require that the client passes the address access restriction and enters a valid username and password.
