I've previously mentioned tools such as, Google Authenticator and LastPass, in regards to helping you manage your online security. I highly recommend Authy as an alternative to Google Authenticator
But what if the solution you want to use doesn't support 2FA(2 Factor Authentication)? That is where Two Factor Auth comes into play. Maintaining an ever growing list of solutions and their current stance on 2FA, they can help you find a solution that does. They even provide a nice little button to help you Tweet to the solution(company) if they currently don't support it or are working on it.
I recommend giving it a look over before you make a decision.
