I think what you did here is perfectly fine. Because shotgun remains agnostic toward UI it doesn't make sense to include console password retrieval support within shotgun itself. However, as with shotgun-client (considering renaming to "shotgun-web-client") you could create a companion library that wraps shotgun and does provide all these helpful features :)
