By default, we do not have this option. You can use the following function code. Please see the steps below:

Note: Make sure to have a complete site backup before proceeding

1. Add a new profile field named "Bio."  Follow this tutorial to learn more about profile fields. 

2. After that, go to Appearance > Theme Editor.

3. Under "Select theme to edit," choose "BuddyBoss Child/whatever theme is active," then click Select.

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

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

//Create the members page's meta description.
//It displays, like John - things entered in the bio field.
add_filter( 'wpseo_metadesc', 'bb_custom_metadata_member_page' );
function bb_custom_metadata_member_page( $desc ) {
  if ( bp_is_blog_page() || bp_is_directory() ) {
    return $desc;
  if ( bp_is_user() ) {

    $args = array(
      'field'     => 'Bio',

    $bio = bp_get_profile_field_data( $args );
    if( empty( $bio ) ){
      $bio = "Some default description, Please fill your bio in Profiles-Edit-Bio.";

    $desc = sprintf( '%s - %s ', bp_get_displayed_user_fullname(), $bio );

  return $desc;

6. Click "Update File" to save the changes.

You can use this function, "bp_get_profile_field_data," to get any data from the member's profile page. In the above example, I took the data from a custom field named "Bio."
