Hi Bitcointalk community,
I'm coming here because I'm desperately in need of your help. I would be very grateful for any advice you have to offer!
So without further ado... My Electrum wallet was set up with 2-step authentication via the Google authenticator app on my smart phone. However, my phone got completely wiped, including all internal and external storage, and I lost the 2-step authentication. Now, I'm unable to withdraw any bitcoins from my wallet.
I have tried to restore the wallet using my seed, but it will only allow me to restore to the wallet type that has 2-step authentication. Additionally, I have tried to restore my wallet on a completely new computer that has never has Electrum installed on it, and again, it only allows me to restore to a 2-step wallet, which then asks for a Google authenticator code when I try to send BTCs out. There is no way for me to get the 2-step back on my phone as all the data was wiped.
Is there anything I can do to bypass or get rid of 2-step on my Electrum wallet? Can I withdraw my bitcoins in some other way? Please let me know. I would truly appreciate your help!
Take care, Frddr

While restoring from seed you should select Wallet with two-factor authentication option, as explained here: http://docs.electrum.org/en/latest/2fa.html?highlight=authenticator#restoring-from-seed In order to restore your wallet from seed, select “wallet with two factor authentication”, as this tells Electrum to use this special variety of seed for restoring your wallet.It should give you access to your wallet.

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

Hey Thomas Here seems not fixed. I have encountered same problem. My mobile has been failed and i have wallet seed. I had 2FA enabled. I am trying to restore wallet by private keys but for some reason i got the "grey" button and i can't go ahead. I tried to select "restore" and then "standard wallet" ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fdl.dropboxusercontent.com%2Fu%2F12098726%2Fshot.jpg&t=665&c=L_sVQlq_pk6TxA) Any idea?

In 2.9.3, you want to go to "File -> New\Restore -> Standard wallet -> I already have a seed"... Enter your 2FA seed... You will then be asked if you want to "keep or disable 2FA"... You can either "keep" and reset your Google Authenticator... Or you can select "disable" and it will create a special wallet that had 2 of the 3 private key chains required to sign the transactions. You can then send the BTC to a new wallet. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ftalkimg.com%2Fimages%2F2023%2F11%2F15%2FzWcA9.png&t=665&c=nUPymv_-z98wug)

There was another user that had similar issues when trying to restore a 2FA wallet, but I can't find the thread or remember exactly what it was that fixed the issue... ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) Possibly it was fixed by shutting down Electrum, removing the blockchain_header file from the Electrum data directory and restarting Electrum... But I'm not 100% sure on that. It's also possible that it is a network issue and Electrum is having trouble connecting to a server nfor whatever reason... You could always try on another PC and see if that helps. Meanwhile I'll see if I can locate the other thread...

Thanks for all the tips, in fact i managed to restore my wallet by renaming the blockchain_headers file in bh_old, electrum then asked me 'keep or disable' and the process continued. What surprised me in the end is that the window still displays [2fa] in its title
Cheers

Technically, it is still a 2FA wallet, as it was created using the "2FA" seed, it is just that you now have 2 of the 3 seeds stored within your wallet file, so electrum can sign all your transactions with 2 private keys without needing to contact TrustedCoin.
You'll notice that all your addresses are still "3" addresses, so you might encounter difficulties with "signing messages" and/or getting a "private key" for any of the addresses in your wallet. A restored 2FA wallet is not really meant for day to day use, but more as a way to recover funds should the TrustedCoin service be unusable for any reason (ie. their service is down, they go out of business etc).
IMO, It would be advisable to either create a new standard wallet (with a single seed) or a new 2FA wallet (with a working GAuth code) and move your funds to that wallet.

I am getting a new phone and was wondering how to move the 2fa to the new device. Will I need to restore the wallet, disable 2fa and then again enable? If so, will I need to pay again for the 2fa service?

That depends on what app you use for Google Authenticator... I use Authenticator Plus, it allows you to backup and restore all your "secret keys", so you can migrate to a new phone without issue. I'm not sure what backup options the "original" Google Authenticator app has... It was one of the reasons I started using Authenticator Plus... You might also want to check out "Authy"... I've heard good reviews about that. "Disabling" the 2FA wallet by restoring from seed DOES NOT disabled the 2FA secret in Google Authenticator... and when you restore and select "keep" it'll ask for the old code or make you reset it... so it *should* be OK... I'd highly recommend attempting to setup the new phone BEFORE you dispose of the old one so you can test it is OK.
