Home of WP-Members, The Original WordPress Membership Plugin

Here is a simple method for allowing users to log in with either their username or their email address.
This process allows the user to log in using either their username or their email address. It’s not difficult to implement and leaves you with a clean process where you don’t have to worry about what to do when users change their email address.

If you using a plugin to implement a CAPTCHA on the WordPress login form (the backend login, wp-login.php), you will find that this is incompatible with the WP-Members front end login.
What happens is that in order to implement the CAPTCHA, the plugin must remove the function wp_authenticate_username_password from the authenticate process with remove_filter. This allows the plugin to implement its own authentication that includes not only username and password, but also will validate the CAPTCHA.
This creates a problem for WP-Members which also uses WP’s authentication to log a user in because the WP-Members form will only be passing two parameters, username and password, and the authentication is now requiring the addition of a third parameter (the CAPTCHA).
