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:

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!
