Thank you!
I'd love to be able to use a Hardware Wallet (i.e., trezor, ledger, etc) to sign in and out and sign anything critical like power down requests, etc.
Unless someone here has thoughts on it, I will Add it to the list of things to research.
(The crypto space being what it is, I have more to research than I could possibly ever actually research, though, so please don't wait on me for any answers!)
