people need a user account on my site to be able to download a plugin. I want to add an activation function in the plugin so a user must supply their username and password the first time they use the plugin to make sure that they have a valid user account on my site before they can use it
what is the simplest way to remotely check a username and password to see if it valid or not from within a php file?
I don't want to enable xml rpc on the site.
