So as some of you that know about the yubi key

I am wanting to use it as the main password for my owner account.
If I long press my yubikey, it does a diceware password

What my aim is to have my password as this : (manual short password) + long press yubikey.

That way you can't just use the yubikey on its own, you need to enter the manual password beforehand.

The problem I have is, I have to enable "USB be accessories"
But the default is "USB accessories only work when unlocked"

What are the realistic risk of having USB accessories enabled? Vs only when unlocked

Is there a way to use my yubikey for the BFU password without enabling the USB accessories on all the time?

Security-wise it does not make sense as USB would always work, even when your phone is locked.
