I’m on Android and would love to see a passcode lock there as well. Do we need to track that as a separate request or can this one be amended to “passcode locks for the apps”?

Because we work on the apps separately, I’ve added a related suggestion for the Android app.

I have a few apps on my iOS devices that can just be set to request re-authentication with the device lock method when opening (passcode, touch-id, faceid) as an alternative to having a unique passcode. I really like this method, as it becomes almost seamless with faceid.
