Transferring login information on one website to another login page

Question

I have an internet service. They provide a login page for accessing the Internet (for example: http://globalNetSolutions.com/Login.html ). If I buy one website (for example: http://MyNetSolutions.com/Login.html ), is it possible with my username and password at http://globalNetSolutions.com/Login.html (due to the fact that a third-party site does not look grate.i wants to log in from my own site.)

I need changes when I can change my code:

<form action="" method="post" onSubmit="">
    <h2>LOGIN TO <span class="red"><strong>MyNetSolutions</strong></span></h2>
    <label for="username">Username</label>
    <input type="text" id="username" name="username" placeholder="choose a username...">

    <label for="password">Password</label>
    <input type="password" id="password" name="password" placeholder="choose a password...">
    <button type="submit">LOGIN</button>
</form>
