Yes, through the MyEtherWallet web interface. Just connect with TREZOR (guide available in the link above)

Trezor warranty has always been one year. I had one malfunction within 30 days and it was replaced free under warranty. Most hardware wallet owners keep more than one on hand just in case of unexpected failure. For comparison KeepKey warranty is also one year. Ledger Nano S is two years.

Any plan to add Litecoin to the wallet?

Is that possible?

How can i use two trezor devices under the same computer?

Nope, to have two different wallets. I would like to save bitcoins on both devices.

BUT, I just found this out and it is pretty cool:

1) Open wallet.trezor.io
2) Attach the destination Trezor (the one you want to send Bitcoins to)
3) Detach the destination Trezor - but REMEMBER it
4) Attach the source Trezor (the one you want to send the Bitcoins from)

Now you can send Bitcoins from the source Trezor to the destination Trezor by getting the next address from the receive dialog of the destination Trezor and copy/paste the address into the send dialog of the source Trezor.  The cool thing was that the wallet.trezor.io "knows" you are doing this and shows you that the destination address is from a Trezor and which Trezor you are about to send the Bitcoins to - a very useful "double check" before you send the Bitcoins.

You can actually connect several Trezors and remember them all when you disconnect them.  You can then get receive addresses from all of them all day long and send as many transactions to them as you want - without any of them being connected.

You only need to plug in one of them when you want to send Bitcoins from that Trezor.

Of course when you are done you can forget all of them so that others will not be able to see all of your addresses and transactions.

I wonder if all my bitcoins are safe or if I need to move all my coins to a new 24key seed?

I have many bitcoinadresses containing BTC, recently I made a small send where I sent 0.20btc to a person.

before sending any btc to anyone just recieving btc this is how it looked (I have modifed adresses and amounts)

for this example I use 1btc/each adress and 10 adresses total:

1. 1aaaaaaaaaaaaaaaatqwt (first and oldest btc adress in trezor)  ----> unspent
2. 1bbbbbbbbbbbbbbbtewt (second and second oldes in trezor)  ----> unspent
.....
10. 1kkkkkkkkkkkkkkkngjf (10th adress in trezor)  ----> unspent

all 10 each have 1 btc so 10btc total.

now after I made a 0.20 btc payment in trezor this is how it now looks when I check blockchain:

1. 1aaaaaaaaaaaaaaaatqwt this is completely spent, so all bitcoins are gone.
0.20 btc has been spent and gone to right reciever 0.80btc has gone to adress 1zzzzzzzzzzfda and is unspent.

1zzzzzzzzzzfda that holds 0.80btc is unspent but I can't see it in trezor over my btc adresses?
trezor still shows correct my balance 9.80btc (the remaining 9 adresses all are unspent)
