Auto completion vs electrum

[Sayounes]

Hello everyone here
I’m just testing electrum wallet and see that after creating the seed it asks for confirmation about it
When you try to confirm the seed there’s an auto completion for words you are trying to type
If you write a word wrong it will disappear (the auto completion )
Is that normal
Regards

Yes it's a norm when putting your seed phrase generated by electrum for you for confirmation. If you put the wrong word it will disappear because electrum knows the 12 word seed phrase for any wallet that you create. This is how electrum will know if you are the real owner of the wallet or not because two different wallet created cannot have the same seed phrase. So auto deleting shows that it's the wrong word that you typed.

I see
Electrum generated the seed but it doesn’t need to know it when you are typing it
It just makes me think it has a dictionary or database from where it generates the seed

It's not that your seed phrase is stored on a database.
By default, electrum uses BIP39 wordlist when generating a seed phrase. The wordlist includes 2048 words and once you enter a word that is not listed there, electrum can know that the seed phrase is not valid.

Ok got it
2048 words from where it generates the seed
No security issue here I think so

There's no security issue on generating a seed from Electrum wallet they use the BIP39 word list but take note the seed generated from Electrum can't be imported to other wallets because Electrum has a versioning system generated from the BIP39 wordlist by default.

For me, if you generated this seed in Electrum in an online machine, I can't say your seed is safe. If I were you, if you want a wallet to be safe and secured, I suggest create a wallet on an offline machine or a cold storage. That's the safest and most secured way to generate a seed phrase from the Electrum wallet.

This is how electrum will know if you are the real owner of the wallet or not because two different wallet created cannot have the same seed phrase. So auto deleting shows that it's the wrong word that you typed.

The aim from asking users to retype the seed is not to prove ownership of the wallet but to ensure they have written it down/ backed it up.

The auto complete feature is there to help users type their seeds fast and to avoid typo mistakes. This feature is also available when you want to restore a wallet.
Electrum will read the letters you typed, compare them to 2048 words on the BIP39 wordlist then it will show you the possible matches.

No it does not. It just means the word isn't in the electrum dictionaries. You can generate a seed with a different dictionary and restore it without supplying the custom dictionary you used.

Also electrum doesn't know all the seed phrases out there. It can't possibly know them all. There is no database of seed mnemonics. It simply hashes the seed mnemonic to see if it begins with a version string and that tells it that it's a valid electrum mnemonic or not.

It is normal. If you type a wrong seed word, you can not click on Next button at the bottom. Because it's a non custodial wallet, and if you did not back up your wallet mnemonic seed, or back it up inaccurately, it's useless for your wallet recovery later. Electrum has this mandatory confirmation step, to make sure that you actually have an accurate usable wallet backup.
