So the expires option will matter now!

custom word list isn't required to restore the wallet from seed. you only need it to create the seed.

for example you can restore from the seed below that is created using this wordlist:

No electrum would still have access to your private keys so you would not be safe just because you extended the seed.

are the words in the mnemonic in this list too:

If yes then you could have a blockchain.info legacy wallet. This is a non-hd wallet and the mnemonic is used as a password reminder. You will need to enter the mnemonic on this page here to get the password:

https://blockchain.info/wallet/forgot-password

You will also need the wallet UUID which is a long hexadecimal number. You can find that by searching your email archives for emails from blockchain.info. You can then login here:

https://login.blockchain.com/#/login?product=wallet

If you can't find the UUID try using an email address instead.

his wallet is synced according to the screenshot.

charlie574 why don't you post a screenshot of the history tab without blacking out the details? It looks like the last transaction is an outgoing one instead of an incoming one.

He made a thread with a screenshot on reddit:

Electrum servers use bitcoin core to interact with the blockchain so that's why the message is from core.

He's using an outdated version of electrum. He won't be able to connect to any server with it. He should upgrade to the latest version.

just backup the wallet file via file > save backup and transfer it to the new pc. open it via file > open or by clicking on the choose button in the opening screen.

you can't convert a standard wallet into a 2fa wallet.

umbrel is free software.

there is no 4.4.2 version. make sure you are downloading it from electrum.org. there are many fake sites out there with coin stealing versions of electrum.

private keys are only exposed if the pc has key stealing malware on it. because the malware is on an internet connected device it can communicate your private keys to the thieves while if it was on a permanently offline device it couldn't communicate the keys to anyone.

the offline wallet is not up to date with the state of your wallet. you have the watch only wallet for that purpose. the offline wallet can't access the blockchain so it doesn't know about your transactions. this is by design.

It does say x/3 signed. In the top left of the advanced transaction preview window.

After one signature it shows this. See status in the top left:

you should make an issue on github then. email the developers your mpk and they'll attempt a restore and find the bug:

try restoring from seed in a fresh wallet file

TOTP code checking can't be decentralized since you need to store the shared secret and the more servers have that the greater the risk of it being compromised. You can instead create a 2fa wallet of your own using multisig between two or more devices.

2fa fees are for outgoing transactions i.e. spending money not for receiving money.

There's nothing wrong with spending an unconfirmed utxo.

see here for things you can try:

You're going to have to hope that the master private key corresponding to the master public key of the 2fa wallet is stored within the 2fa wallet file. So first open the 2fa wallet and go to wallet menu > password and disable the password there i.e. enter it in the first field and leave the other two blank. Then go to file >save backup to save the wallet file somewhere convenient. Open it using notepad or some other plain text editor and ctrl+f the mpk Zpub6y9TQbtUj3ux3BAMcFBwGnrd98eLCwWo8rzTvgRFnL42dpAdcYU4smYSGuLZ9NpAVkXeLUgSCMZ CvD6G9AC7zWi4nL2UF1ReJBTwgnwn4kN. Next to it you should see the Zprv like in the following example:


If the zprv is not there then you have to restore the 2fa wallet from seed and then search for the zprv in the restored wallet file.


Copy that Zprv and restore a multisig wallet in electrum. Start via file > new/restore, select multisig wallet type, 2 of 2  and enter the seed for the first cosigner and the zprv for the second. Now you should be able to spend from the wallet.
