What is the most secure way to generate a 12 word seed for a hardware wallet. I would like to also add a passphrase.
Usually, it's best to just use whatever procedure the hardware vendor suggests... The brain is a terrible source of entropy, so whatever method you're using not suggested by the vendor, it's usually worse than just following the proper procedure.
This does not mean there aren't good ways to create a 12 word seed yourself, but usually your own methods aren't more secure than the recommanded methods anyway (imho)
The hardware wallet I want to purchase can only generate 24 by default. In my opinion the only way to be secure from seizure of your funds is to memorize the seed. With 12 words it's much easier. This is why I need to generate the 12 words.
I am sure someone can help with this. Explain it to me, I understand I may need to purchase an offline laptop which is ok.
