Since your question is specifically about Electrum seeds, it would make sense to post this thread in the Electrum subforum of the wallet software forum

Well, Electrum is not perfect to give you a 100% secured wallet; it still depends on your environment. The seed generation from Electrum is unique and not compatible to any other wallet when importing.

I'm using Electrum for me; their wallet seed generation is sufficient to me since I haven't experienced any issue yet from my wallet. I generated my seed in an offline device; it was never connected to the internet. I only use a separate device only for signing an offline transaction I use the camera or SD card to transfer the raw unsigned transaction to the offline device to sign the transaction and scan it via QR code to broadcast the transaction into the online device.

I know it does not have some feature where the mouse movements are included to generate a unique seed, but the quality of the Electrum seed depends on your device environment.
The only reason why most users are being hacked and lose their BTC is due to malware like installing a fake Electrum and also being attacked online if you can make a cold storage wallet with Electrum you are far from any online attacks.

About adding a passphrase, this feature actually exists in Electrum as extended custom words. It makes your seed phrase more secure if you enable it during wallet creation.

You either trust that multiple eyes have reviewed and audited the code or you look and verify yourself. Electrum is well designed and a long time on the market. Well, that doesn't prove anything if everybody kept their eyes shut.


This is quite some bullshit, don't believe every nonsense you read anywhere.


You can tell Electrum via the console tab to produce 24 recovery words, if that makes you feel safer.

You're wrong when you say "there is no option for any of this". When you create a standard Electrum wallet new, on the screen where the Electrum recovery words are shown, there's an "Options" button, click on it, ans "Seed Options" opens where you can tick the box "Extend this seed with custom words". Here you can specify the additional mnemonic passphrase. It can be anything, not necessarily only some custom words. Beware! The smallest error in the additional mnemonic passphrase and you don't get your wallet you expect but just another empty wallet.

If you extend the seed words (the mnemonic recovery words, by standard 12, but you can instruct Electrum to generate more; I will have to look up the command for it) with an additional mnemonic passphrase, it's very important to properly document and backup both, but not together!

Enter this in the Console tab to generate 24 recovery words for an Electrum Segwit wallet (standard). If you don't see the Console tab (not enabled by default), enable it from the "View" menu.

Electrum gets its random entropy from your operating system's cryptographically secure pseudorandom number generator (CSPRNG) via Python underlying system calls (such as os.urandom or secrets.token_bytes).  Modern operating system CSPRNGs are highly secure because they use true physical entropy (chaotic noise) from your computer hardware.  The problem with the Coldcard was a critical firmware bug that caused certain devices to generate weak, predictable seed phrases.  Instead of calling the secure hardware TRNG, the device silently defaulted to a weak, predictable software-based PRNG fallback.

Disregarding the "AI breaking ECDSA FUD" that you've read, Electrum should now be strong against AI-assisted "hacking".
One reason is; the latest 2 release versions were extensively audited by famous people/group that utilizes AI (while not entirely relying on it).
Not just one, but a few of them, refer to Electrum's release notes for the list.

So, if even there'll be an obvious but missed vulnerability in the entropy generation like Coldcard firmware had or even a sneaky one,
It should've been caught months ago.

But since a bug is something that's unintended, we'll never know for certain.
But assuming AI is already used to audit the code, there's only a slim chance that a basement dweller hacker can find something that they've missed with another AI.

AI can't speed up bruteforce,
But it can potentially speed up the development of hardware and software that can be used to bruteforce.
But then, it depends if it can invent something so efficient that doesn't require to harness the sun's entire energy to power it.
