- Before Android 6 (API 23), there was no KeyStore yet. Currently, you can still create an encrypted account, but the passphrase is stored in clear-text, because that's how Signal is doing things.
- There is no option to manually set the keyphrase or to unlock via fingerprint. This has the advantage that we never need user input for unlocking the accounts and can simply unlock all accounts on startup and the obvious disadvantage that anyone with access to the unlocked device can open DC.
- Each account is encrypted with a different passphrase.
- When importing, you can choose to encrypt the account.
