Trezor One/ Trezor Model T questions..

[Pmalek]

Since you are using a Trezor device that has an unfixable seed extraction vulnerability that was mentioned in the previous posts, I would suggest you consider extending your seed with a passphrase for extra protection. Alternatively, you can also activate SD protection in Trezor T that allows you to save a secret code on a microSD card. That card would then be required every time you unlock your device to gain access to it.

Trezor T creates 12 word seed phrases by default, while the Trezor One creates 24 word seed phrases by default. However, by using the command line interface you can generate a 12 or 24 word seed phrase (or a 18 word seed phrase) with either device. You can also restore seed phrases of 12, 18, or 24 words to both devices, so your plan of restoring your 24 word seed phrase from your Trezor One to your new Trezor T is entirely possible.

Thank you for this info!
I'm sure it's easier than I think it is.. I'm just afraid of doing something wrong and losing my coins ( I know I know.. their not on the wallet, hahaha )

When I get my new Trezor Model T, I might be asking a few more questions.

1. What important things is Trezor T generated 12 mnemonic seed only, which is different from Trezor one generate 24 seed.
2. You can directly enter the passphrase in Trezor one device with a touchscreen.

Thank you for this info.. so the Trezor Model T is a 12 word seed.. but looking at that link you provided, it can be a 24 word.

oeleo gave your correct info.  BUT:

** This info below has been mentioned well above in this thread but the OP still seems to be asking questions making me think he has missed this point:

I wanted to add something just as a precaution for you, not knowing how you have handled the 24 word SEED from your Trezor ONE.  The key to secure SEED is that it is never entered on any computer that is/has been online.  In other words "assume" the computer you connect any Trezor to is infected (its a safe way to paradigm).  When you setup the Trezor 1 you would have written the SEED down on a piece of paper and NOT placed on a computer (hopefully).  During setup the T1 would cycle through the SEED words on the device screen and you would write them down.  Good if that is how you did it!  Now over time IF you ever restored that Trezor ONE, meaning you had to enter the SEED on the device again, it would ONLY have been possible using a screen on your computer/Android.  That could be VERY bad if the computer used is an online machine either currently or in the past.  Your new Trezor T can be easily restored by entering the SEED words ONLY on the device screen itself leaving the computer out of the process, which protects the security of the SEED (it NEVER sees a computer during the process).  This is especially easy using trezorctl, in fact SIMPLE.

I typed the above to say that IF you ever exposed your SEED to a computer that is NOT AirGap, installed using offline Tails, or a similar RAM based method it might be wise to consider a NEW SEED setup.  Creating new SEED on a Trezor T is fast and secure.  Of course this means you would have to transfer the coins from the old wallet to the new one.  If you are using bc1 address format its not that costly to be sure your SEED has never been seen on any computer.  Easy for me to say/type because I have been at this for 10 years now, LOL!

Thank you Coin Keeper!
When I originally set up my Trezor One, I had my laptop offline. I wrote down the seeds on a sheet of paper that was provided, so my seeds have never been on my computer or online. I did do it the way you have mentioned.. so that is good news!

Now if I understand this correctly, If I can use the same 24 word seeds on my new Model T, then there won't be a fee for moving my coins over from the old Model One to the new Model T?
If that is correct, then I just need to follow the instructions when I get my new Model T and transfer my current 24 word seeds to it.

If I can't safely figure that out, then my new Model T has a 12 word seed. If I just go with that, then there would be a fee for transferring from my old Model One to the new Model T?

Sorry again for having to keep figuring this out.. I'm just nervous about all this and afraid of losing coins somehow.
I can't find any videos on YouTube that show how to do what I'm talking about.

Correct.

Yes, you would have to pay a transaction fee.

Hardly anything can go wrong. As long as you keep your Trezor One untouched, you will still have access to your coins.

You are correct that there will be no fee, but the reason there is no fee is because your coins don't move.

As we said above, your coins are not stored on your hardware wallet. Your coins are on the blockchain and never leave the blockchain. What your hardware wallet stores is the private keys which let you access these coins. Your seed phrase is used to generate these private keys. By importing your seed phrase to another hardware wallet, you are duplicating your private keys across both devices, so both devices can access your coins, which haven't moved.

If I can't safely figure that out, then my new Model T has a 12 word seed. If I just go with that, then there would be a fee for transferring from my old Model One to the new Model T?

In this case there would be a fee. By generating a new seed phrase you are generating a new set of private keys. If you want to transfer your coins from the addresses linked to your old private keys to an address linked with your new private keys, then you need to make a transaction to move the coins. Note that the coins only move from one location on the blockchain to a different location on the blockchain. Again, the only thing on your hardware wallets are the private keys allowing you to access those coins.

Thanks again you guys!
Feeling better about this now and understanding it.

One last question..
Since I don't have my new Model T yet, I was watching some YT videos. I bought the Model T so I can see/access my Cardano on it.
Do I need to go through a 3rd party website to actually do that?
Daedalus, Yoroi, and Adalite?

Trezor Suite is not supporting cardano so you will have to connect your device with AdaLite or Yoroi wallets, (Daedalus is not supported) and I think that same support is for ledger wallet also.
You don't need to use any 3rd party websites, just download wallets and connect them with your Trezor hardware wallet.

dkbit98 has answered this question correctly, you will need AdaLite or Yoroi wallet. For more help, you can use this link, Cardano (ADA) - Trezor Wiki to know the procedure of how you can use AdaLite which can also be helpful while connecting Trezor with Yoroi.

Thank you again!
Bummer why these companies can't get it all compatible..
Trezor One doesn't support ADA
Model T supports ADA, but Trezor Suite doesn't.
Gotta get another site just to see my ADA..
DUMB!

on wallet.trezor.io you will find Cardano on the list, just click it, you will direct to an external wallet; https://adalite.io/
choose hardware wallet and unlock with Trezor.



Just be careful if you manually write the URL, there is much phishing similar like adalite.io domain,

Your expectations and reality are two completely different things, because no hardware wallet supports all possible coins/tokens through its interface - they all use third-party wallets for 99% of all coins. I guess it’s about the technical possibilities to make something like that, because every unique coin requires its own blockchain, which requires even more infrastructure and complicates things.

What is positive and only important is the fact that the hardware wallet gives us the ability to store our private keys in a secure environment - and for some other things we have to invest a little more time. If you want to deal with altcoins, be prepared for some compromises.
