Starting in August, installing APKs from unverified developers will require a new procedure called Advanced Flow. It involves enabling developer mode, rebooting the device, and waiting 24 hours with biometric verification.
After that, you choose: allow the APK installation for 7 days or indefinitely. The procedure is a one-time process and applies to all versions of Android.
Will the 24-hour wait stop you from installing APKs outside the store?


It means there is no demand for KYC, as you suggested.
Yes, you do. Unless you are developing an app just for your friends, or you expect everyone not on a custom ROM to go through the ridiculous “advanced flow”.
The above is from the official update by Google.
No, you don’t.
That is the expectation.
If you expect regular users to go through with this ridiculous process you are just naive. Anyone who distributes their app through something like F-Droid will either, have to choose between going through with giving Google their ID or lose 85% of their users, if they are lucky.
What I expect is not up for debate. The fact is that your statement is wrong.
Anyone who can go through the current process can easily go through this new one.
