Reply To: Edit the bbPress login widget

untested, but try this

add_filter ('bbp_get_user_profile_link' , 'rew_get_user_name', 10 , 2) ;

function rew_get_user_name ($user_link, $user_id ) {
	// Validate user id
		$user_id = bbp_get_user_id( $user_id );
		if ( empty( $user_id ) ) {
			return false;
		}

		$user      = get_userdata( $user_id );
		$user_link = esc_html( $user->display_name ) ;

		// Filter & return
		return apply_filters( 'rew_get_user_name', $user_link, $user_id );
}

Put this in your child theme’s function file – or use
