How can I be sure second Metamask FTM wallet is on Trezor?

I have one full wallet of nodes (FTM) and so I need a second wallet.

I made a second account and have set up an FTM wallet there but it doesn’t have a hardware flag like my first FTM
Account wallet has.

How can I be certain the second wallet is secure?

Tell us about your creation process. Maybe you created MM wallet instead of MM-trezor wallet.
