By default, the platform does not have this option. You can use the following function code to adjust the login page width.

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 custom_login_logo() {
  echo '<style>
    body.login.login-split-page #login {
        width: 370px;
    }
  </style>';
}
add_action('login_head', 'custom_login_logo');

5. Click Update File to save the changes.
