Let Siri do her job in lock screen

So you need to ask Apple to add a switch for every app that would allow you to choose whether the app should be accessible from the lock screen or not. https://apple.com/feedback is the place to do that, not here. If enough people think it's important enough to ask you may get it.

the answer here is very simple you practically proposed it yourself already.

Important "sensitive" Apps have a seperate passcode themselves, so there is no problem at all by letting Siri open all remaining apps the way the user wants to. When one allows Siri to "work when locked" that means exactly that.

Then tell Apple that you'd like to see that:

The real issue is what apps can be opened without a passcode, which is the same thing as saying what apps can be opened by Siri from the lock screen.

There are some apps that it would be OK to open without a passcode, and others that definitely would not be OK to open without a passcode. I leave it to the reader to find examples of each, but I have a few in mind. The problem is that Siri has no way of knowing which are OK to open and which are not. With almost 2 million apps available it's an impossible job, unless Apple adds a switch for each app in, say, Settings/Privacy, that would let a user select apps that it's OK to open without a passcode.

I am riding on my bike with the headset on and I ask Siri to open Spotify and play a song. I have granted lock screen access to Siri but still she keeps on telling me that I have to unlock my phone in order for her to do the job and open an app.

How can I adjust the settings to get her working as expected?

Siri can do lots of things from the lock screen. However, if you want to open an app you have to enter your passcode. That is how is supposed to work. Siri has somewhat more access to Apple's built in apps from the lock screen than it has to third party apps. For example, if you say, "Hey, Siri, play some music", Siri can play music from the built in Music app without unlocking the phone.

You can certainly submit feedback to Apple here:

Go to Settings-Search & Siri and make sure the options you want are toggled on.

Then press the Power and Home buttons until you see the Apple logo.

If that does not work, there may a firmware incompatibility with the headset so check for an update from the manufacturer.

Are you sure about this? Name one reason why this is how it’s supposed to work (actually not work, see the problem?)

Yes, I'm pretty sure about this. As to why, for the same reason anything works the way it does on an iPhone: because that's the way Apple decided to make it work. At a guess, I'd say for security reasons. If you can open apps without a passcode using Siri, what is the point in even having a passcode? Your phone is no longer secure.

Clearly Siri can access the most sensitive Apps like Phone, Contacts and Messaging. So there goes point number one. Point number two: What about thinking in favor of the user's security instead of the phone security?

Phone security IS user security; they are not separable. Suppose the police seize your phone. Under your scenario they could say "Hey siri, show any **** on this phone." Or, if you live in a repressive country where you could go to jail for messages you send, so you use a secure messaging app such as Signal or Whatsapp, "Hey Siri, open the Signal app"
