You have the option to restore your wallet from seed in Electrum without the 2FA feature.

Click on "Create new wallet" > "I already have a seed" and enter you seed. Enter the correct seed of your 2FA wallet and after that there should be an option to restore the wallet with 2FA disabled. Click on that and you are all set. You can then spend from this wallet without being asked for the 2FA code.

But you should know that you will be creating larger transactions and pay bigger mining fees since you are using a multi-sig setup. Once your wallet is recovered, create a new standard Electrum wallet with a new seed (one that isn't 2FA) and move your coins to that one.

You are using a 2FA Electroneum wallet, hence 3 keys (inform of multi signature) are required to proof ownership of your UTXO.
If you have the passphrase (private key), kindly import it into a new electroneum wallet and Disable the 2FA when it pop up and you are good to go.

No passphrase? You wouldn't be able to spend from your wallet.

You are using a 2FA Electroneum wallet

Electroneum and Electrum are two different things. Electroneum is an altcoin. Something to do with virtual mobile mining. Electrum is a bitcoin-only, open-source software wallet. 

If you have the passphrase (private key)

Recovery phrases and private keys aren't the same thing. By putting "private key" in brackets, you make it seem like they are. A private key is only associated with one public key. All private and public keys and addresses are generated from the seed.
When people say "passphrase", they usually talk about the seed extension, aka the 13th or 25th word of the seed.

What did you mean by passphrase?

The 12 word recovery phrase is called the seed phrase, while extending the word with extra words or characters is the passphrase. If you do not have seed phrase (+pass phrase if included) you will not be able to recover your bitcoin.

But in your case, you can still access the wallet, which means getting your seed phrase should not be a problem, but best for the seed phrase to be backup offline including the passphrase but differently.

Just follow Pmalek reply, you will be able to recover your coins and setup another 2fa wallet on Electrum or move it to standard electrum wallet.

I am speechless right now.
I need more lessons. Thanks.  

I have understood the seed phrase. The seed phrase houses the private and public key in every wallet.
Please how can a seed phrase extension used to create a passphrase?

Passphrase is added to the seed phrase to increase the security of the wallet.
If you add a passphrase to your seed phrase, your wallet will generate completely different addresses. In the case your seed phrase is compromised, the hacker or the thief can't access your fund without knowing the passphrase.
The passphrase can include any character (uppercase letters, lowercase letters, numbers, symbols and space).  

In electrum, you can click on "options" and check "Extend this seed with custom words" to add a passphrase to your seed phrase.

The passphrase is not used to create the seed phrase. The passphrase is an optional security layer that you can add on top of the seed phrase to increase the overall security of your wallet.

To simplify what hosseinimr93 was talking about.
If you have a wallet protected with a 12/24-words seed phrase, and someone finds your seed, that person can spend all the coins from that wallet.
If you have a wallet with a 12/24-words seed phrase, plus an additional passphrase, the hacker would need both to spend your funds. The seed alone wont give him access to the coins protected with the passphrase.

You will see the difference if you play around with that feature on Electrum. Create a new wallet on Electrum just for testing the passphrase feature.

• Create one standard wallet without a passphrase.
• Save the seed somewhere.
• Open the wallet and save one of its addresses.
• Now restore your wallet from the same seed and you will find the same address that you saved previously.

• Create a second wallet, restore it from the same seed as above.
• During the restoration process, extend the seed with a passphrase.
• Follow what hosseinimr93 suggests in his last sentence on how to do that.
• Open the wallet and check its addresses.
• You will notice that it has a completely different set of addresses compared to the first one without the passphrase.
• Try to find the saved address from wallet 1. You will notice it's not there.

For the purposes of this test, it's ok to save the seed digitally. It's faster to copy/paste it to restore the wallet. But you should never do it with a real seed that holds your coins.

For Electrum "2fa" wallets you need:

1. Wallet + Wallet password (if any) and 2FA code from Authenticator

or

2. 12 word seed recovery phrase


Without one of these, you're screwed. As mentioned, there is a possibility that if you contact TrustedCoin (https://api.trustedcoin.com/#/contact-us) from the email address you originally used when you setup the 2FA wallet, you might be able to get them to reset the authenticator for you.

I have heard people mention that a few times on the forum, but do we have any stats or confirmations that TrustedCoin is willing to do that? If they do, getting access to someone's email could be enough to reset the 2FA feature. Luckily, that information alone is not enough to steal someone's coins.

I am fairly sure it has indeed been reported by people on threads here that they were able to get TrustedCoin to help... like this one: https://bitcointalk.org/index.php?topic=5071869.0

and this one: https://bitcointalk.org/index.php?topic=5127850.msg52959353#msg52959353


I'm fairly certain there have been others, but the forum search tools aren't the best and it's late I have no idea if TrustedCoin still do this, or what they actually require in the way of proof that you are legitimately the owner/creator of the wallet... but there appears to be anecdotal evidence that they might.

The first link that you posted explains some of the things they ask. According to the OP who wrote it, they will request that you send them one of the receiving or change addresses or that you tell them the total balance of the wallet, or maybe the amount on one of the UTXOs. I think that is OK.

It seems that having control over the email address used at the time of registration is enough for resetting the 2FA. They send a new code to that email address.
Read the post made by Tryninja. He sent an email to trustedcoin support and asked them how to reset the 2FA.
