Never.
The company bought the phone, their policies call for long secure passwords for all computers & devices. It's been like that for the fifteen years I've been there.
Our BYOD policy finally allows me to use an iPhone, I'm not going to complain because the Touch ID system is not acceptable to the powers that be. Especially since we're very well compensated for our work.
No reason to stir up trouble. A very experienced, large scale, secure design company, I'll continue to trust them.
Seems like they need to loosen up a bit about Touch ID. You can have your long ass password and use Touch ID to access it for yourself only. But it's great that you're "very well compensated" for your work.
