Can one auto-authorize based on visited IP?

This plugin doesn’t do it out of the box.
However you can use a filter to do this.

Something along the lines of:

function password_protected_check_ip( $bool ) {
	// Check the IP address here and return 0 (ie disabled) if you want to allow the IP address
	return $bool;
}
add_filter( 'pre_option_password_protected_status', 'password_protected_check_ip' );

Awesome!! Thanks very much Ben. Will try to implement now.

AND, it works!

In case anyone comes across this looking for the solution, it is as simple as this;

function password_protected_check_ip( $bool ) {
	// Check the IP address here and return 0 (ie disabled) if you want to allow the IP address
	if($_SERVER['REMOTE_ADDR'] == "160.79.66.166") {
	$bool = 0;
	}
	return $bool;
}
add_filter( 'pre_option_password_protected_status', 'password_protected_check_ip' );
