By default, the platform does not have this option. You can use the following function code to change the Sign in color.

Please see 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 “?>”:

add_action( 'login_enqueue_scripts', 'customLoginStyle' );
function customLoginStyle() {
  $styles = '<style>
.login .login-heading h2 {
    color: #ffffff;
  echo $styles;

5. Click Update File to save the changes.
