Hello everybody,

I just set up my Trezor One and I see option to set additional protection with passpharse.
However I heard that while it may make things safer,it can also be devastating if I forget it,or lost it.
Some say it's not recommend to use it,other say it's great extra layer of protection.
I would like to know your opinion.

Also,I set up my Trezor and download Trezor Suite app for desktop.
I wrote seed words as well as PIN.
I would like to know is that all and am I now completely protected from any kind of threat like hacking or pishing attacks?
