1  Bitcoin / Electrum / Re: Help please.. Lost 2-step authentication on Electrum on: February 19, 2018, 11:27:22 PM
If I've lost the seed is there anyway to get Electrum to generate the 2fa code again?  Sending the coins out of the wallet isn't an option as I don't have the password - but am looking at getting it back.   Thing I'm most concerned about at the moment is losing my phone/having it stolen and then have no hope of getting the coins back as I don't have access to the 2fa code.
The seed will give you the 2 private-keys from your wallet of 2-of-3 scheme. This means that you can use the seed to "disable" the 2FA and spend without the 2FA code. But you can't generate the code from the seed.

If you lost the seed, the only thing you can do is send all your coins to a new wallet, since losing the phone means your coins are gone. But without the password, it shouldn't be possible without the seed to restore the wallet.


For some reason I got an email with a different reply from you saying talk to Trusted Coin and see what they say - maybe you wrote an initial post then edited it? I did talk to them and they resent me the QR code which is what I needed - so thank you for your reply even though it's not appearing in this forum.

Hi bitbaby, thank you so much for your reply. I did indeed select "wallet with two factor authentication" but unfortunately, I have lost the Google Authenticator data from my phone (internal storage has been completely wiped and is irretrievable). So I am able to see my funds in my wallet; however, I can't send them out anywhere because it will ask for the Authentication when I try to do so. Is there anything else I can try?? Thanks again

no, it will not ask for the second factor after you have restored from that seed.
the seed contains two master keys.

EDIT: 2.6 and 2.6.1 have a bug, that breaks what I just wrote. I will make a new release today

3  Bitcoin / Electrum / Re: How to manually decrypt Electrums encrypted seed and xprv from wallet file on: January 05, 2018, 11:32:35 PM
You need the password to decrypt it. If you don't know the exact password but have some idea of what it might be you can attempt to bruteforce it. That means to try various combinations of passwords until you hit the right one. You can bruteforce it using btchris' script given below or hire someone to do it for you:

https://github.com/gurnec/btcrecover

However you must have at least some idea of what the password might be for bruteforcing to be feasible.


I also attempted to use the decrypt_electrum_seed code from GitHub but kept getting the messages unexpected seed_version: 13 and KeyError : 'seed'.  The same error is produced by wallets that have a password and wallets that don't have a password so do you have any idea what else might be causing these errors?

I think the file mnemonic.py on the decrypt_electrum_seed page possibly contains the words the code uses to try and decrypt the wallet but I could be wrong.  If this is the case then the problem may be in the fact that some of the seed words Electrum generates when new wallets are created are not contained within the mnemonic.py list of words?

But the code might be using a more up to date list than the one shown in mnemonic.py and the problem might be being caused by something else.
