Just be aware that the security benefits that you're getting on a Hot Wallet with 2FA will be reduced based from your machine's security alone though.


I understand what you mean, but someone who has 2FA in their Electrum wallet should be far safer than someone who doesn't when it comes to the security of the device on which the wallet is installed. Even if someone compromised their computer with malware/virus capable of stealing any sensitive information regarding the wallet, they would not be able to steal the coins since the last piece of the puzzle is located on another device that generates 2FA.

In some more sophisticated attacks, the hacker could try to get the data related to 2FA if the owner is naive enough to hand it over to the hacker. It's no secret that there are those who fall for the cheap tricks of the Electrum customer service.

If you have your wallet’s seed, you can disable 2FA if you want by following this guide: https://bitcointalksearch.org/topic/m.63584947 written by Husna.
He already paid the 0.0012 BTC 2FA Service Fee for 100 transactions, it would be a waste to disable 2FA now since it will not be refunded that way.
He can take note of those instructions for the future at least.

Sorry, I've already found, that was just billing for 100 transactons.
And you can monitor how many prepaid transactions you have left by clicking the Trusted Coin Logo on the lower-right hand side of Electrum.
Useful if you want to disable it before you run out of prepaid transactions if you don't want to pay for the next 100.

I assume you are using Electrum and that your wallet is a 2FA wallet (you can check the wallet type in the title bar on desktop versions and in Wallet Details on mobile versions).

The first address is the one you are sending the coins to, the second one (in blue) belongs to TrustedCoin, and the third one is your change address.

Hello! I used this wallet the first time and encounter a problem. I did the first transaction from it (0.001btc was the necessary sum) with little commission. But when I finished it, I saw there were 3 outputs for all the sum of my wallet - the necessary address for those 0.001btc, 0.0012btc to some unknown address marked with blue colour and the rest of sum returned to the second my address for reception.
Please, help me, what does mean this blue address? I haven't it in my list of created addresses, active or frozen. Now I can say my 0.0012btc are just lost.
