S2member password strength indicator Translate

I have a free version of s2member.
I would like to know if there some way i can translate the output for the passord strength indicator. I’ve translated every other line, but i can’t figure out how to do this last thing. Can you help me?

Try this:

function kts_text_context_changes( $translated, $original, $context, $domain ) {
    if ( $domain == 's2member' && $context == 's2member-front' ) {
        if ( $original == 'Strength indicator' ) {
            $translated = 'Whatever you want to say';
        }
    }
    return $translated; // return modified text
}
add_filter( 'gettext_with_context', 'kts_text_context_changes', 10, 4 );
