Hello, I need help of the community.

When creating a 2FA wallet in electrum i have a problem. I already have a seed and I want to use that but after entering the seed the button appears in grey (desactivated). It means that the seed it's not recognized. Any idea why it's happen?What can I do to use my own seed?

 

Buddy when you enter the seed words you need to put space between each word. Did you do that?Click "Options", select "BIP39 seed", DO NOT TICK ANYTHING ELSE . Usually if the seed words are correct automatically the button will be enabled. When prompted for the "Derviation Path", enter: m/0' . If you have any other doubts, just contact this member (https://bitcointalk.org/index.php?action=profile;u=867786)of this forum by clicking the link. Definitely he will be able to help you.

Yes, the blanks are fine and words are EXCATLY the same. I am using a BIP49. Is that a problem? :)

Two important things to note:

1. 2FA wallets use a special seed that are unique to Electrum 2FA wallets (and detected by the application as such). The seeds are "special" because they actually generate 3 different master private keys. The first gets put into the wallet file, the second is "hidden" unless you disable 2FA functionality when restoring and the third is owned by TrustedCoin. The result is that you cannot, as far as I'm aware, use custom seeds for Electrum 2FA wallets.

2. 2FA wallets will charge you extra fees for the 2FA service. You have to "prepay" for 20 or 100 transaction credits, 0.002 or 0.005 BTC respectively. (read more here: https://api.trustedcoin.com/#/electrum-help) These charges are ADDITIONAL to the normal bitcoin transaction fees.


If you want to use a custom seed, you can only use it with a "standard" wallet.

Thank you HCP! I tried different ways to use a custom seed and none of them work. It seems to me that you're right!! Thank you for your help!
