Whats a good lower cost way to implement two factor authentication when using bitcoin wallets?

I was expecting a different question in here when I saw the title and I can't answer the OP's question, sorry.

But what I was wondering is if there had been any consideration to implementing two factor authentication in any of the bitcoin clients? Passwords can be guessed, or discovered through key-logging, but with 2FA enabled the coins could not be spent

Yeah I do really good passwords but I'm afraid of keylogging. Lets me ask something else, does the application have to support 2FA or is there another way?

Passwords are awful. You should check out LaunchKey. It's a passwordless multi-factor (possession, inherence, knowledge) solution. If you want to see it in action and get a feel for the user experience you can use this wallet: https://faucet.launchkey.com
