By paraphrase, you are referring to the password I'm typing each time I open the wallet, right?
No, that's your password and is used for encrypting your keys locally. You don't need that password if you recover the wallet using your seed phrase.
Passphrase is different from password. Passphrase is extra words or characters added to the seed phrase. If you add a passphrase to your seed phrase, your wallet will generate entirely different keys.
In electrum, when you create a new wallet and generate a seed phrase, you can click on "Options" and check "Extend this seed with custom words" to add a seed phrase to your seed phrase.
If you didn't do so when generating the wallet, there is no passphrase and the seed phrase is enough for recovering the wallet.
By paraphrase, you are referring to the password I'm typing each time I open the wallet, right?
No, that means you did not include passphrase (not
paraphrase) when you created the wallet.
In Electrum, the passphrase is regarded as extended word. If you just want to create a new Electrum wallet, you will have the option to extend the seed with extra words, but it is optional. The extended word will lead to generation of different keys and addresses entirely, that is why it is mandatory while restoring/importing the wallet to include the passphrase.
I understand now, I didn't enter a passphrase when generating the wallet, thus, I'll only need the seed phrase to restore my wallet. Thanks again!
you can backup the wallet file via file menu > save backup in electrum. Later on the new installation you can open the wallet file via file > open or by clicking on the browse button in the starting window.
Might try that one too, just in case it comes in handy.
Firstly, I'll try restoring the wallet in another PC I have, just to see how it works and make sure I do everything correctly.
Many thanks to all of you!
