This might be a dumb question but can’t seem to find a clear answer online.
If I make a Monero wallet with a Trezor, the Monero seed is hardware protected and you aren’t able to see it. If I lost my Trezor device and got a new one, put in the Trezor seed and can see all my crypto again on Trezor Suite, would I still be able to go onto the Monero GUI and access the old wallet, or would it be unrecoverable?
I’m sure it would be stored on the seed, if that’s even the right way to say it, cause that makes much more sense, but I just have to double check.
As long as you store your Trezor seed and additional Trezor passphrase (if you use one), losing or damaging the device doesn’t matter.
You can simply purchase a new Trezor device and restore it using your Trezor seed and additional passphrase (if applicable).
Regarding the Monero wallet, I assume you are referring to the Monero GUI wallet.
It’s highly likely that the private key generated in the Monero GUI wallet is derived from your Trezor wallet (and thus, your Trezor seed). In summary, as long as you remember your Trezor seed and additional passphrase (if used), you will be able to recover your Monero wallet in the future.
Appreciate the reply but you just re-worded my question lol. Already well aware of your top two points, I did mention the GUI wallet and I also concluded it’s highly likely it would be on the seed. I’m looking for actual yes or no confirmation though
you’re getting confused there with the “monero seeds” and “trezor seeds”
Trezor stores exactly one seed at a time. This single seed derives all addresses and private keys – including, obviously, your Monero keys.
There is no “Monero seed protected by hardware” in play: if you use Trezor together with Monero GUI, the Monero GUI app becomes in essence a “viewer” of the addresses owned by the Trezor, backed up as part of the Trezor seed.
all your coins are, technically, saved on the respective blockchains.
but all your addresses and keys are part of the same seed, yes.
(it’s not “saved on” it, there’s no data being added to the seed. the seed contains enough information to generate all the addresses that you’ll ever need)
U2F, yes.
If you are using FIDO passkeys, however, those are installed into the device separately, and are not part of the seed. You can back them up via a trezorctl command, unfortunately this functionality is not currently part of Trezor Suite.
(how to tell the difference? general rule of thumb: if the login doesn’t need your password, and if you see your username on Trezor screen when logging in, it’s a FIDO passkey. If you only see the website, it’s U2F)
Thank you for the answer. Good to know that i need to do additional backup when i use FIDO but not when i use U2F because U2F is also derived from the same seed phrase
