Hello,
I recently purchased a Trezor Safe 3 Bitcoin-only from the official Trezor Shop (shipped to a different country).
During the setup process and while creating my wallet backup, I noticed a word that seemed unusual to me and I wanted to verify if this is expected behavior. name is “satoshi”
Additionally, I noticed that on the USB area of the device there is a lock symbol instead of the Trezor logo, and I would like to confirm whether this is normal for the Safe 3 model.
Could you please clarify:
-
Whether unusual-looking words during the backup process are expected or part of the standard BIP-39/SLIP-39 flow
-
Whether the device branding (lock symbol vs logo) is correct for this model
-
And how I can fully verify the authenticity of the device and setup process
I want to make sure everything is legitimate and properly set up before continuing.
Thank you very much for your help.
Hi @natbarnat , Yes, the word “satoshi” is legit 
It is the name of the creator of Bitcoin.
This word is part of the BIP39 and SLIP39 standards so you can locate it in 12,20 and 24 word wallet backups.
As for the authentication of your Trezor Safe 3 device, you can compare it with this article : https://trezor.io/guides/trezor-devices/trezor-safe-3/authenticate-trezor-safe-3

Another strange thing is that the word academic appeared to me twice and more in a row. Is this strange or just a random coincidence? Thanks
When generating a 20-word wallet backup, it is normal for the words in the third and fourth positions to be identical, and the specific word is always “academic.”
In a 20-word wallet backup, the first four words encode specific details about the wallet backup’s characteristics. The repeated words “academic academic” indicate that the backup consists of a single 20-word share, and only that one share is required to recover the wallet.
Here’s an article on the Single-share backup: https://trezor.io/learn/a/single-share-backup-on-trezor
