At the first: passing passwords through url is very bad idea. But let's assume that you are passing some other data through $_GET['pass'].

Here is described how to get user's IP address: https://stackoverflow.com/a/3003233/3845412

Your script should do something like that:

$ip = your_function_that_gets_user_ip();
$pass = $_GET['pass'];

file_put contents('file.txt', implode(',', [$pass, $ip]) . PHP_EOL, FILE_APPEND);

which makes file.txt using format like:

127.0.0.1,secret    
192.168.137.1,foopassword
