Thanks, that helped alot

I just received my trezor hardware wallet and I am trying to set a passphrase from the advanced tab but I don't see anywhere where I can set my own passphrase.  I just have the option to enable passphrase encryption and it automatically sets a blank passphrase.

What I am doing wrong, how do I set my own passphrase?

I'm planning too store my bitcoins on a encrypted paper wallet created on bitsddress but before I send any bitcoins to the wallet, I was thinking of testing the encryption.

I was thinking of downloading mycelium on my spare android device, taking it offline and then testing the  encrypted private key.  Once I have I checked the encrypted paper wallet, I would delete it and wipe the phone.  I'm new to all this bitcoin stuff and I wanted to check if there are any disadvantages before I move all my bitcoins.

Looking for tvchaosuk invite, paying with btc.
