Or would be, if Apple devices did not routinely prompt you for your password. I find this incredibly annoying since my Apple ID uses one of those long, irregular passwords automatically generated by password managers and in the context where Apple wants your password there's no way to cut and paste it. I can use my phone with touch ID to authorize a $20k purchase but if I want to install a free app from the App Store I need my stupid password. I wonder why they do this.
I haven't had to enter my Apple ID password to install an app since I setup my phone. Just Face ID verification. Maybe you have this setting toggled? https://support.apple.com/en-us/HT204030
Or maybe Apple is just deciding to require it from you for mysterious reasons. Your IP could have a bad reputation and they're not sure if it's you. Though I think they sometimes they require the password just to keep you from forgetting it.
If they insist on this, I think it would be nice if they rigged their backend to allow me to enter the password from any of my devices. They already allow this from the Apple TV+ app on smart TVs, so the technical precedent exists within Apple.
