two different seeds generated from the same ledger using the python script

[5HAK0]

Hi everyone,
I have been trying to recover my 25 words monero seed from my ledger using the python script , and I successfully did it...BUT...
something weird happened. I did both procedures, online and offline 25 words generation, and the results I get are different.
This is a bit scary, and I can't think of any explanation...I repeated the procedure twice and it gave me the same result, I also verified my ledger 24 word seed, it matches.
So, to recap :
Procedure 1 (offline) -> I generated 25 words from the 24 words ledger seed -> Got 1 result
Procedure 2 (online) -> I generated 25 words directly from the ledger -> Got a different result

Does anyone have any idea how that could be and did I miss something ??? I thought there would be only one monero address generated, else the whole thing would be pointless, if I were to lose or break my device, I then would lose everything, not being able to recover properly from my 24 words seed...Fortunately, now I have written down the 25 words of the wallet where my balance is, but I'd still like to understand the subject better and find an explanation.

Thanks for your contributions

Are you using an additional passphrase linked to PIN with the Ledger?

Can you please confirm :

• If you use a passphrase on your Ledger hardware wallet ? (This is also sometimes called a 25th word... although it's not the same as the 25th word used by the monero wallet).

If you use a 25th word or passphrase on your Nano, the seed becomes de facto different from your original 24 words. This could explain why you get a different result when retrieving the 25 monero words directly from the device.

• if you have followed the procedure from this page ? https://github.com/LedgerHQ/ledger-app-monero/tree/master/tools/python

Thanks

Hi,
I have not set any passphrase on my Ledger Nano, and yes I have followed the instructions on the aforementioned page.
Thank you guys for helping!

Could you please confirm the Monero app version you are using ?
Also can you please tell us the FW version and device type (Nano S or X) ?

This way we'll try to reproduce.

HI Fabrice, yes indeed, the Monero app version is 1.7.8 and my device is a Nano S with firmware 2.0.0

Thanks a lot for your attention
