Okay, I've built a TOTP key widget and it works perfectly. There's one glaring problem, and that is that it works while the phone is locked, so anyone can just swipe and see all the keys. Is there any way for the widget to know if the phone is locked or not?

I'd like for it to work if the phone is unlocked, but not necessarily off the lock screen. Similar to how the widget for the Files app works.

StackOverflow says to check for

UIApplication.sharedApplication().isProtectedDataAvailable()

Though I have not tested in the widget.

UIApplication.sharedApplication().isProtectedDataAvailable()

Works perfectly. Only thing to note is that it doesn't return False unless the phone has been locked for ~10 seconds or more. That's perfect, thanks!
