Ok, thats something important to know. So when the service dies, but you still have your brainwallet, you will be able to recover your funds? I mean without the service could you create the multisig addresses again at all? I would not know what to do just in the case.
Again: YES. How many times will I need to repeat that?
Yes, you can recover your wallet from its seed, at any time, even if the service dies. It is fully deterministic.
Competing services may not have that feature, but Electrum does have it.
I would certainly not propose that service in Electrum if it was not the case.
Is it your service?
The service is operated by TrustedCoin.
The fees paid by users are shared between Electrum Technologies and TrustedCoin.
The service was developed by both companies.
If not, why didnt you implement 2FA normally? Not being able to log into the account or send transactions without 2FA should have been sufficient i guess. Why not going that route? The service costs money for each transaction on top. Because of that i doubt many will use it.
what the F*** do you mean by 'normally'? If you mean 'without a remote server', then you can create a multisig wallet with Electrum, and sign transactions with two devices; it will not cost you anything. It even works with android.
OTOH, if you want the convenience of someone else hosting and securing a cosigning key for you, then someone has to pay for the server operation, and for the people developing the service. I do not want to run that kind of service on VC money (like BitGo does), because I want Electrum to remain independent, and because it does not work in the long run (what do you do once you run out of VC money?)
