New PinCode

[SaschaDe]

Hello everyone,
I have now updated my historically somewhat grown installation to the latest version. The current version no longer allows the pin code 1111-1111.
What happens if I enter a new pin code here now?
Will all HomeKit devices be removed and re-added?

I would hate to remove all devices because then I would have to rework all my automations.

Thanks and regards
Sascha
