Recommended Encryption Settings
We recommend a KeePass (KDBX4.x) format database. This allows a configurable Key Derivation Function. For your KDF, we recommend Argon2d or Argon2id, both are nice GPU resistant KDFs. You should set the memory to around 32MB. Higher memory settings (especially anything above 64MB) will cause i... -

Can I Trust That Strongbox Is Not Stealing My Passwords?
The only 100% sure-fire way would be for you to read the code, understand it, compile it, and deploy it.

How Does Strongbox Perform Against RAM Dumps or Memory/Debugging Attacks?
The threat of someone being able to access the memory of a running instance of a program is a notoriously difficult one to protect against.

How Secure Is Face ID / Touch ID?
While Touch/Face ID is very convenient, it is not a perfect system for protecting your passwords. It is provided for convenience only.

Configuration Issue: Convenience Unlock and Quick Launch with Device Passcode Fallback
With a certain sequence of settings enabled, you can make your database more vulnerable to attack. The Strongbox app attempts to warn you about this, so that you can take a suitable action or at least be aware of the issue.

Choosing Argon2 or Argon2id As Your Key Derivation Function (KDF)
It's pretty marginal either way on this. Some say Argon2id offers better defence against side channel/timing attacks, others that this is irrelevant in a client side app situation. We don't take a strong stance, both are solid and we support both. You can read more of the original KeePass devel... -

Apple introduced the App Privacy section to the App Store in 2020 to give users a better idea of the privacy implications of using an App. This is to be applauded.
