OK. After seeing numerous posts and having to respond to repeated claims that "2FA coins are not under your control", I'm now feeling compelled to clarify the issue here.

Based on MY best understanding, the so called two-factors coins are actually exactly the same as the so called private-key coins in their physical shape and form as well as their material composition. The ONLY difference between the two is HOW the private key is handled. Perhaps that is the point - people having or believing they have the private key sealed on the back of the coin tend to feel that they are in total control when the facts are:

- You won't know if a private key is there until you unseal the coin.
- An average person wont' be able to tell if a private is valid or not until that person actually tries to redeem the coin, as the company could misprint and printed the wrong key.
- You won't know for sure the non-existence of another copy of the private key somewhere else.

Thus, when you purchase a private key coin you must take a FAITH in the business that you're dealing with, cause it is not possible for you to rule out the risk above in advance.

Now, if you have faith in a company for all of the above, why would you not trust them for 2FA coins? Perhaps, you worried about them losing the private keys? I tend to believe the odd of them losing the private key databases is no greater than me losing the coins. Reason? Those private key databases are encrypted so they can easily backed up and have multiple copies stored at different places (it's even safe to save them in the cloud). Given everything done properly it's still the decryption key printed inside the security seal of the coin that matters, which is in your hands.

Hope this is useful.
