I think the IB solution is a dongle that plugs into a USB port. Theirs is probably fine, but I bought one of these: http://www.guardidsystems.com/ It can be used for many password-protected sites. I believe the IB (and others) solution is for their site only. I could be wrong about that, but I don't think so. I haven't yet installed the ID Vault dongle on my machine, but I'll give a trip report when I can.
