Password Protect Staging
Password Protect Staging
Description
Enable, set a user and PW via WP admin and users will be prompted via HTTP AUTH for a user/pw before being able to view the frontend.
Aim of the plugin is to protect staging sites from the prying eyes of search engine robots, and to keep out anyone who might stumble across it accidentally.
This isn’t particularly secure – password is in the database.
