The topic of this list is R, not security. For the purposes of this mailing list the user needs to take responsibility for the password. If you want to take that responsibility (cache it) from the user then you need to talk to experts on security so you can become one yourself.

IMHO obfuscating a password is worse than leaving it plain, because that would be misleading the user about how securely the password is being managed.
