This article goes into more detail about how these new measures will actually work compared to the blog post earlier this year from Google. Namely:
- Enabling the OEM unlocking setting will no longer prevent FRP from activating.
- Bypassing the setup wizard will no longer deactivate FRP. FRP restrictions will apply until you verify ownership of the device by signing in.
- Adding a new Google account is blocked.
- Setting a lock screen PIN or password is blocked.
- Installing new apps is blocked.
I also imagine FRP will be ignored by custom ROMs even if the secret data is set.
Well, that won’t matter unless it’s a brand new phone or has been properly erased because you won’t be able to install lineage anyway unless one of those two conditions are met.
