Escape PIN
The Escape PIN is for situations where you need to make your real vault disappear immediately. When you enter the Escape PIN, Privara permanently destroys the real vault: all files are wiped, encryption keys are destroyed, and the app silently opens the decoy vault instead.
To anyone watching, it looks like you simply opened the app. There is no trace of the real vault or its contents. Set your Escape PIN during setup and use it only when you need this level of protection.
