[Quickwin] Use general message for a required PIN
Currently, there are three cases where you need to enter your PIN:
- After booting into the system
- After some time (for extra security)
- When in lockdown
The message that a PIN is required is different in each of these scenarios. We shall not distinguish between them because this leaks information. This leaks the information if a user has voluntarily enabled lockdown mode. This can be used against a user.
I propose a message like "PIN required" or "PIN required for security" or "PIN required after boot / after lockdown or for extra security"
Alternatively add a option to make the message generic.
I suggest to remove any kind of message on both PIN screen and lock screen. Why does one need a hint? They can just know that they are required to enter the PIN if lock screen brings them to the PIN screen.
