It's a valid concern, but we don't offer a key token, that's what the iphone is for - a secure device in your hands. In addition I can offer these recommendations:

1. Secure your pc with antivirus and all other best practices recommended by your computer vendor. Upgrade to latest version of the OS (Mac Snow Leopard or Windows-7).
2. When away from your PC always use the iPhone app instead of someone else's PC.
3. Do not use memengo web site on unfamiliar computers unless you absolutely must. For example if I lost my wallet and my iphone in a foreign country I would use memengo web site to get a credit card number to buy a plane ticket home, but then I would change all of the passwords and keys (and maybe even credit card numbers) when I return home.
4. If you must enter key on a foreign computer consider copy-pasting letters from the screen instead of typing them to reduce the keylogger threat.
5. Create separate wallets in memengo wallet for data of different sensitivity. For example, create one wallet for all your casual forums and web sites which you don't care about and give it an easy to remember key, create one special wallet where you store only one credit card number to be used in an emergency like I described, and also create one other wallet where you store the rest of your stuff and you only use from your trusted home computer.

Hope that helps!
