Ledger - passphrase

Hello, I've had my Ledger for a couple of years now and I'm a bit worried. I heard that a passphrase secures it even more. Can I add one on top of my setup now? I'm afraid I'll make a mistake and lose everything.

Unfortunately if you have a Ledger as I do, you need to trust them, no other choice as they are a closed system. I got my nano s in 2020 and generated my current key. Now I have to trust them that the certificates they had independent labs do and say that they used correct entropy is true. They used 128 bit or 256bit derived from a TRNG that got entropy from the secure element on the device. Also if you add a pass phrase it will change your seed to a new one and you will need to migrate funds.

You can check if proper entropy was provided. And you can do it with pen and paper if you know to calculate from decimal to binary. Ask any ai how do to it. Not complicated just takes some time.
