I was able to transfer my bitcoins to a new electrum wallet that I created with a password and an extended mnemonic seedphrase. My question is this safe enough or would I have to create a new wallet with a password, extended mnemonic seedphrase AND also add 2FA?
As long as no one has access to your seed phrase (a series of 12 words) and your passphrase (the words or characters you entered to extend your seed phrase), your fund is secure.
@hosseinimr93 As for the passphrase that you mentioned, what do you mean exactly? is this different from the seed phrase and the password?
The 12 words electrum gave you is called seed phrase.
The words or characters you added to your seed phrase when creating the wallet is called passphrase.
What you need to enter when opening the wallet or sending bitcoin is called password.
If you don't use any passphrase, the seed phrase is enough for recovering the wallet.
If you use a passphrase, for recovering the wallet, you need both seed phrase and passphrase.
Note that your password is stored locally and is used only for encrypting the wallet file.
Anyone has access to the seed phrase (+passphrase if there's any) doesn't need the password.
What if my system gets compromised and someone has access to the 12 word seed phrase BUT not the pass phrase (extension words), is it still safe? As for 2FA, I feel like I should add that for extra security, is it necessary? My concern for 2FA is if it goes missing, then what?
