For a few years now, there's also been the option on Android to avoid giving permanent permissions to most apps that request use of one; when an app requests a permission for the first time, I'm prompted to choose from the options "allow only this time", "allow only while using the app", or "allow always" (in addition to having the option to completely deny the permission of course, although in many cases an app might refuse to function if that's chosen). Scanning TOTP QR code seems like a really great use-case for the "allow only this time" option; presumably adding a new TOTP secret is a pretty infrequent reason for opening the app compared to getting a code from an existing one, so having to manually accept the request each time doesn't seem like it would be that much work. I'm not familiar with with iOS to know if something similar to this exists for it, but I'd honestly be more surprised if there _isn't_.
