More clarification on entropy sources for Trezor/Ledger HSMs #13
Description
The disadvantages section of both Trezor and Ledger say that the entropy source is controlled entirely by ARM:
I think it would be beneficial to clarify that the user can use their own external entropy as a source by importing a BIP39 mnemonic seed phrase.
If this has been carefully generated via a scheme like diceware then it's literally just using the universe as it's entropy source.
In my opinion this is a huge advantage of these two devices.
