GOS21606 Is it possible to change a PIN for a current profile into a Password ? And are changing the keys of this profile as well or only the access PIN/ PW ?
GOS21606 Litmus9 It does not effect the security when you first set up a simple PIN during installation and after that change it in a long pass word/ phrase? And I am talking about the owner profile.
other8026 GOS21606 I'd suggest reading through this section of the website: https://grapheneos.org/faq#encryption. Here's a couple relevant parts: User profiles each have their own unique, randomly generated disk encryption key and their own unique key encryption key is used to encrypt it. Even if you use the same passphrase for multiple profiles, each of those profiles still ends up with a unique key encryption key and a compromise of the OS while one of them is active won't leak the passphrase. The advantage to using separate passphrases is in case an attacker records you entering it.
GOS21606 Thanks for your reply, I read the section before. The only question was does it matter if I change the pin afterwards from a 6 digit pin into a difficult passphrase. No I understand there is no difference from a first setup.
