Recall sits in a secure vault behind BitLocker encryption secured with Windows Hello.

BitLocker+Windows Hello gets broken through, the world has a much larger problem than some screenshots, because that's the foundation of, like, 80% of enterprise security.

If you're afraid that an attacker sits on your PC and just waits for you to unlock the vault, then you already have the PC breached to the point where they don't have to do that, they already have access to everything else.

If you're afraid of the feature in anyway, don't use it.
