By default, the platform does not have this option. You can use the following function code to remove/hide sign-in button on the login page.

Please follow the steps below:

1. Go to Appearance > Theme Editor.

2. Under “Select theme to edit”, choose (BuddyBoss Child/whatever theme is active), then click “Select”.

3. Below Theme Files, select Theme Functions (functions.php).

4. Append the code just before the closing PHP tag “?>”:

function bb_login_custom_css() { ?>
  <style>
    body.login .login-heading h1{
display: none !important;
        }
  </style>
  <?php }
add_action( 'login_enqueue_scripts', 'bb_login_custom_css');
