Joey10076 Hello, this is mentioned on the website: https://grapheneos.org/features#duress
If you ever create a secondary user profile with a password as its unlock method, or change your primary profile's unlock method to a password, you'll want to be sure that you can continue to use duress.
The alternative would be for the user to choose if they wanted one or the other, which I imagine would cause a lot of users to forget to, say, add a duress password in addition to a duress PIN if they ever changed their unlock method from a PIN to a password.
